Single-stage FZ type pumps

Application

Type FZ impeller single-stage pumps are used to pump clean and dirty water, municipal and industrial waste, as well as other liquids, depending on corrosion resistance of materials of which the pump is made. They constitute a highly-unified family of submersible and dry-installed pumps. There are different versions of these pumps, depending on the characteristics of pumped liquids and the type and size of pumped impurities. In particular, they are applied in the pumping of sewage, including sewage with solid and long-fibre content, as well as liquids containing air and gases. They will work very well in pumping of raw sewage containing active sediment, and putrid sewage.

Basic types

Type of pump Discharge port diameter Connection type
FZ.1 DN 50 threaded/flange
FZ.2 DN 65 flange
FZ.3 DN 80 flange
FZ.4 DN 100 flange
FZ.5 DN 125 flange
FZ.6 DN 150 flange
FZ.7 DN 200 flange
FZ.9 DN 300 flange

Versions

FZA For pumping water, liquid manure solutions, or contaminated liquids without any inclusions, with the diameter of up to 6 mm.
FZB Channel impeller pumps for pumping contaminated liquids with solid and sewage content, without fibrous substances.
FZP Channel impeller pumps for pumping clean and slightly contaminated liquids.

FZA


The FZA type pump is equipped with a multi-vane one-side open impeller for pumping water, liquid manure solutions, faeces, contaminated liquids, gassing liquids without abrasive precipitations having a diameter larger than 6 mm, and fibrous impurities. There are no internal motor safety devices in the FZA pumps. The drive motor in the FZA pump is "wet" – it is filled with white mineral oil according to the PN-60/M-96105 standard. The pump is only available as FZA.1.

The FZA pumping units may be applied for one of the following or other uses:

  • small intermediate pumping stations for domestic and industrial sewage;
  • in sewage treatment plants, as auxiliary pumping units,
  • horticulture,
  • construction industry,
  • farming,
  • emptying private septic tanks,
  • utilisation of rainwater,
  • water removal from flooded buildings,
  • emptying pools and tanks.

FZB


The FZB type pumps are equipped with a closed channel impeller. The pump is used for pumping contaminated liquids with solid and sewage content (e.g. water with sand) and without fibrous substances.

The characteristics of these systems:

  • high efficiency of the hydraulic system;
  • less “free” passage as compared to Vortex systems.

The pumps of this type are used in sewage pumping stations with seperation of solids manufactured by Hydro-Vacuum SA, but they can also be used for pumping other liquds than preliminarily cleaned sewage.

In the standard version (1), the impeller is made of Zl250; and in version 2, the impeller and bearing housing are made of ZbCr32. At the customer’s request, the pumping housing may also be made of ZbCr32 or cast steel.

The B value (“free” passage) for FZB:

  • FZB.1 – ø 6 mm
  • FZB.2 – ø 15 mm
  • FZB.3 – ø 32 mm (for FZB.3.90 - ø 15 mm)
  • FZB.4 – ø 45 mm
  • FZB.6 – ø 55 mm
  • FZB.7 – ø 80 mm

FZP


The FZP type pumps are equipped with a multi-vane closed channel impeller with spatial curvature blades. These pumps are used for pumping clean water, and water contaminated with sand.

The characteristics of these systems:

  • high efficiency of the hydraulic system, higher than in all of the above, up to 84%;
  • lower NPSH as compared to the FZB pumps by using wider inlet and a spatial blade.

The standard material for the impeller is Zl250 (version 1), and in version 2 the impeller and bearing housing are made of ZbCr32. The FZP type pumps are also available in a cast steel version.

Drives used in FZ pumps

Motors cooled with pumped medium, with IP68

Uses:

  • sewage pumping station (wet);
  • rainwater and drainage water pumping station;
  • pumping out substances from holding tanks.

These drives are applied in the following pumps:

a) Pumps with motors filled with white mineral oil, and not equipped with sensors inside the motor chamber:

  • FZA.1 ,FZB.1 (except 60-69), FZV.1, FZR.1

b) Pumps with "dry" motors, but without extra sensors inside the motor chamber:

  • FZB.1(60-69), FZB.2, FZB.3, FZB.4

c) Pumps with "dry" motors, equipped as a standard with moisture and thermal bimetal sensors inside the motor chamber:

  • FZB.1(60-69)
  • FZB.2
  • FZB.3
  • FZB.4


Air-cooled motors with IP55 – monoblock pumps

Uses:

  • sewage pumping station (dry);
  • water, rainwater and drainage water pumping station (dry);
  • sewage pumping stations with seperation of solids;
  • private systems.



Air-cooled motors with IP55 and standard flange-type motor

Uses:

  • sewage pumping station (dry);
  • water, rainwater and drainage water pumping station (dry);
  • sewage pumping stations with seperation of solids.

These drives are applied in the following pumps:

  • FZB.5, FZP.5
  • FZB.6, FZP.6
  • FZB.9


IP68 motors with internal cooling system and non-submersible operation capability

The internal cooling system operation:

  • the motor is cooled through the internal cooling system which removes heat from the motor frame, and transfers it to the pumped liquid through the wall between the motor and the pump;
  • the coolant used in the system is a glycol and water mixture, which enables it to work at low temperatures;
  • the movement of liquid in the internal system is forced by an axial impeller with low energy consumption;
  • the internal system is fully separated from the pumped liquid, which prevents bacterial fouling, as is the case in systems cooled with the pumped medium, such as municipal waste;
  • the pressure in the cooling system is low, regardless of pump parameters, which reduces the risk of system unsealing.

Uses:

  • dry pumping stations with a risk of flooding by rainwater;
  • sewage pumping stations with seperation of solids with a risk of flooding by surface downflow;
  • conventional intermediate pumping stations for sewage, rainwater etc.

These drives are applied in the following pumps:

  • FZ.5, FZ.6, FZ.7, FZ.9
