Liquids handled

Deep-well pumps are designed for use in handling raw or treated potable water, sea water, as well as for mineral and thermal applications, with no long fibers or abrasive content.
Mechanical impurities in the liquids handled may be up to 100 mg/l of water; for pump units where impellers and stators are made of plastic, they may be up to 50 mg/l of water.
Impurities that might cause creation of deposits in the pump and on the motor are inadmissible. If this is unavoidable, the deposits of 0.5 mm maximum must be removed.
Liquids liable to cause accelerated corrosion or erosion of the pump construction materials must never be used. Liquids other than water may be handled subject to manufacturer’s approval.

Motors used in deep-well units

Deep-well pumps manufactured by Hydro-Vacuum S.A. are fitted with wet-type submersible electric motors. Other types, ones having a fl ange connection and dimensions according to NEMA, may be used, if required.

Cooperation with frequency converters

All deep-well units manufactured by Hydro-Vacuum S.A. and equipped with three-phase electric motors may have a frequency converter drive.
Recommendations:

avoid operation of submersible motors at higher than nominal frequencies, i.e. 50 and 60 Hz;
the power rating of the submersible motor selected ought to be one magnitude higher than the standard motor power rating, matching a given pump;
the permissible minimum frequency is 32Hz, provided that a minimum rate of flow past the external motor surface of 0.2 m/s is maintained; it is advised to use a suction jacket for the purpose;
use RC and LC filters to protect the motor from harmful over-voltage and interferences;
select a frequency converter that matches the nominal current rating of the motor;
the frequency converter ought to incorporate safety devices, protecting the motor from:
- over-current,
- drop of supply voltage,
- phase decay.
the frequency converter ought to be supplied strictly in accordance with manufacturer’s requirements, specifically those in respect of feeder-cable cross-sections and keeping the permissible distance between the frequency converter and the motor.
please note that the relationship below applies when changing the current frequency / rate of rotation of the pump unit shaft

Q_x = Q_n * (f_x ÷ f_n)¹
H_x = H_n * (f_x ÷ f_n)²
P_x = P_n * (f_x ÷ f_n)³

General conditions of characteristics validity

For all the characteristics of the pumps shown in this catalogue the following general conditions shall apply:

the characteristics declared above refer to pump units, with motors supplied with electric current at 50 Hz and power output sufficient for the entire pump capacity range
tolerances of pump operation parameters according to PN-EN ISO 9906 Cl. 2 Appendix A
the characteristics are obtained for handling non-aerated water at 20°C and viscosity v = 1 mm²/s
the pump characteristics H=f(Q) include hydraulic losses at the pump inlet and the non-return valve which is built in the pump
power characteristics P=f(Q) show an average power consumption by a single pump stage
efficiency characteristics η=f(Q) refer to a single hydraulic stage of a pump with a nominal-diameter impeller; without taking into account any losses at the pump inlet and the non-return valve
the pump efficiency for several stages or with trimmed impellers is lower than that shown in this catalogue and the efficiency characteristics η=f[Q] may be provided by the manufacturer if requested by the client
the pump works without cavitation if the required NPSH cavitation reserve plus the liquid column 0,5-1m is maintained
for handling liquids other than water please contact the manufacturer: handling liquids of which the density and viscosity are higher than those of water will cause an increased requirement for power at the pump shaft , therefore, a motor with a higher power output has to be used.

In certain situations, the duty point required may be located between the nominal characteristics of the succeeding pump type dimensions. Therefore, intermediate characteristics, obtained by the nominal impeller trimming, are introduced in GC, GD and GF deep-well pumps. In the GC and GD pumps having up to 9 stages, the succeeding trimmings are denoted by the letters A, B, C… and in the GF pump the succeeding impeller trimmings are denoted by the digits 1 to 5. This enables an optimized selection of the pump unit to match the required operating parameters, reduces power requirement on the pump shaft and enables a motor with a lower nominal power output to be selected.

If you are interested in pumps with more than 9 stages and having trimmed impellers, please contact the pump unit manufacturer. It is recommended to select pumps for operation in their high performance range for a more economical operation and maximized service life of the pump unit.

The pump unit may not be operated with the valve on the discharge pipe closed because the absence of flow past the motor makes it impossible to cool it. The recommended minimum pump capacity is not lower than 0,2*Q_max.

Design of deep-well pumps

Deep-well pumps are a multistage type of pumps, constructed in series. They are installed on submersible motors, therefore, they are also referred to as submersible units. The pumping unit is installed vertically, with a submersible motor located at the bottom and the deep-well impeller pump. The suction casing, protected with a sieve filter, is installed straight on the motor. The specific pump stages are installed aft er the suction casing. Each of them comprises the casing and the stator fitted in it, and an impeller (radial or diagonal type). The pump is closed with the non-return valve housing and the discharge casing to connect the pump unit to the discharge pipe using either fl anges or a threaded connection. A coupling is provided to connect the rotating parts of the pump and the motor shaft . Distance sleeves are provided to correctly position the impeller in the stator and pump casing. The rotating unit of the pump has steel-and-rubber bearing bushes

Depending on the deep-well pump type, the pump stages may be connected using either:

connecting tapes (the GAB, GB, GBC, GC and GCA pumps), or
double-nutted bolts (the GDB, GDC and GFB pumps) - individual stages.

Underwater deep-well units are special application pumps. They are compact and highly reliable. They have the following advantages:

low cost (the bore-holes have very small diameters, no buildings over the well are required),
low operating costs,
simple operation (no lubrication points),
fast and simple assembly and disassembly.

Deep-well pumps have been manufactured by HYDRO-VACUUM S.A. since 1939. Experience and ongoing improvement effort have resulted in a series of deep-well pumps of which the operating characteristics and service life are comparable to those of European products. They are used in a number of applications all over Poland: in municipal drinking water systems, in villages, in housing estates, in farming and gardening. They proved very well in tests and have been operated on a regular basis in the brown coal strip mine in Bełchatów and Konin (Poland). At present, they are used in other strip mines and in the construction industry, where low subsoil water levels are required in deep foundation trenches.

Selection of feeder cables

The feeder cables for deep-well units are preferably selected using

the diagram 1 and Table 1 for direct starting motors (see Page 8), and
the diagram 2 and Table 2 for star-delta starting motors (See Page 9).

The diagrams show the maximum lengths of feeder cables, depending on the current output for the supply voltage Un=400 V, a voltage drop of 3 % and temperature t = +25^oC. For supply voltage ratings other than 400 V, the feeder cross-sectional area should be selected using suitable diagrams, adjusting the current output in accordance with the following formula:

I = I_zn * 400

I = I_zn * ------------

I = I_zn * U_zn

For temperatures above +25^oC, the selected feeder cable cross-section should be adjusted with regard to the cable current load limit, based on tolerable current loads given in Tables 1 and 2.

Example:
Select a feeder cable cross-section for a direct starting motor given the following parameters:

supply voltage rating, Uzn = 400 V:
current rating: - 40 A,
required cable length: - 300 m,
ambient temperature: - +45^oC.

From Diagram 1 select the cable cross-section 35 mm² for 40 A current rating and 300 m cable length. For such cable cross-section at 40 A current rating, the maximum tolerable cable length is 360 m. For a length of 300 m, the voltage drop is:

ΔU = 300 * 3% = 2,5%

ΔU = ------------ * 3% = 2,5%

ΔU = 360 * 3% = 2,5%

A smaller cable cross-section of 25 mm² may be used for a current load of 40 A up to a length of 260 m. For a length of 300 m, the voltage drop is:

ΔU = 300 * 3% = 3,46%

ΔU = ------------ * 3% = 3,46%

ΔU = 260 * 3% = 3,46%

A cable cross-section of 35 mm² with 2.5% voltage drop is the right choice.

Checking the current load:
For a temperature of 45^oC and cable cross-section of 35 mm², the tolerable maximum current load for a 3-wire cable is 120 A according to Table 1. Therefore, the cross-section above is suitable and sufficient.

Example:
Select a feeder cable cross-section for a direct starting motor given the following parameters:

supply voltage rating, Un, = 1000 V,
current rating: 100 A,
required cable length: 200 m
ambient temperature: +30^oC.

I = 100 *400 = 40 A

I = 100 *------------ = 40 A

I = 100 *1000 = 40 A

From Diagram 1 select the cable cross-section 35 mm². A current rating and 300 m cable length. For such cable cross-section at 40 A current rating, the maximum tolerable cable length is 360 m. For a length of 300 m, the voltage drop is:

ΔU = 200 * 3% = 1,67%

ΔU = ------------ * 3% = 1,67%

ΔU = 360 * 3% = 1,67%

Another smaller cable cross-section of 25 mm² may be used for a current load of 40 A up to a length of 260 m. For a length of 200 m, the voltage drop is:

ΔU = 200 * 3% = 2,30%

ΔU = ------------ * 3% = 2,30%

ΔU = 260 * 3% = 2,30%

The current load is checked for nominal current rating I_n = 100 A according to Table 1. For a temperature of 30^oC, the tolerable maximum current load is 128 A. Therefore, the cable cross-section above is sufficient.

Selection of feeder cable cross-section for direct star-up:

Motor cooling

Specific requirements are posed as to the rate of flow past the motor:

Type of motor	Rate of flow past the motor	Liquid temperature
	m/s	^oC
MOTORS 4"	0.08	35
SMV	0.2	25
SMS	0.2	30
SMP	0.2	70

Calculation of the rate of flow past the motor:

V = Q [m/s]

V = --------------------------------------- [m/s]

V = 2826 (D_s² - d_s²) [m/s]

Where:
Q - pump capacity [m³/h]
D_s - well inside diameter [m]
d_s - motor diameter [m]

NOTE: For V_calc < V_req a suction jacket is required on the motor, of which the inside diameter suits the desirable rate of flow past the motor.
