Construction

Vertical multi-stage rotary pumps with opposite intake and pumping short pipes ('inline' system). The pump's drive is transferred from a standard flange electric motor by a coupling (clamp sleeve coupling in the OPA.0, OPA.1, OPA.2, OPA.3 pumps and sleeve coupling in the OPA.4, OPA.5, OPA.6, OPA.7 pumps). The upper body of the pump functions as a base for the motor mounting.

Axial forces occurring within the system during the pump's operation are transferred by a rolling bearing, which is permanently mounted inside the head of the pump (does not require manual operation for the entire period of use).

Radial forces are transferred by a slide bearing, which is lubricated with a pumped medium and secured against dry operation thanks to its location – the bearing is mounted in the intake area of the pump's lower body.

The shaft of the pump is sealed with a front (mechanical) seal in the upper body of the pump; the type of a seal is dependent on the pressure and temperature of the pumped medium.

Advantages of OPA, OPB pumps

OPA pumps are characterised by high efficiency and durability, that result from application of the company's own design of pump elements enables customers to obtain the optimal hydraulic systems.

The main advantages OPA, OPB pumps are as follows:

• location of suction-pump ends ("in-line") makes it possible to obtain simpler installation,
• vertical pump layout enables us to save space at the place of pumping unit installation,
• pump design permits using the standard engine (collar from IMV 1 or IMV 18), which makes pump service considerably easier,
• clamp-sleeve coupling ensures simple and problem-free disassembly and assembly of the motor on the pump assembly,
• external jacket together with the circulating water create a "screen" around the pump, which considerably decreases hydraulic noises,
• the location of the slide bearing in the lower casing, always filled with water, protects it from dry operation and avoids fast wearing.

Our products have all the necessary attestation statements (for pumping drinking water and for household purposes), certificates and safety certificates.

Data which should be included in an order:

• When ordering pumps, state alphanumeric marking and full name of executions in the sequence given in the product marking structure.
• Moreover, the following information should be given:
• capacity Q [ m³/h ],
• pump delivery head H [ m ],
• kind of pumped liquid,
• pumped liquid temperature T [ ^oC ],
• hydrogen ion concentration factor [ pH ],
• liquid density p [ kg/m³ ],
• liquid viscosity v [ mm²/s ],
• amount and type of impurities [ g/dm³ ],
• supply voltage U [ V ],
• network frequency f [ Hz ],
• motor start type,
• other data.

In the view of possible modernization of the article, manufacturer has reserved the right for modification of any technical data, which will not a negative effect for quality of the article.

OPERATION AREA

Hydro-Vacuum S.A. Pump Selection Progam.

Quick and simple online tool for pump selection based on set criteria.

Thanks to the PDP, by means of the "Hydraulic Selection" function, specific pumps can be selected by configuring, among other things, the area of application, pump type, pump design, medium to be pumped, operating point, etc. Alternatively, by using the "Product Catalogue", you can conveniently browse through the pump catalogue which is Hydro-Vacuum S.A. 's production offer.

The result of the selection is a data sheet for the pump containing all the necessary hydraulic (characteristics), electrical, material, construction, dimensional, etc. data.

The first thing to do is to register a new account. After entering some necessary data and approving the form, an activation link will be sent to the e-mail address provided. After clicking on the link, you will be able to make full use of the Hydro-Vacuum S.A. Pump Selection Software.

We encourage you to create an account and try our program.
