vertical multistage pumps
vertical multistage pumps
Manufactured almost entirely from stainless steel, which are precision pressed and welded to form efficient hydraulic components.   These pumps are highly efficient and economical.

Features
All stainless steel construction
Quiet operation
Compact size
Single mechanical seal
High efficiency hydraulic design
Stable head-flow curves for parallel operation

Benefits
Flanges in-line to simplify pipe layout.
Suction and discharge pipes are both on the bottom half of the casing, allowing the pump to be maintained without disturbing the pipework.
Low Nett Positive Suction Head protects the pump from cavitation damage.
Non-overloading power characteristics.


Applications
Utilities: Water treatment and distribution
Building services: Jockey pumps for pressure maintenance, booster duties and for boiler feed water.
Industrial: Vehicle washing plant, high pressure water supply.
Process and chemical works: Water transfer, cooling water supply and general services.
Horticulture and golf course watering.

Operating pressure
Standard pumps are capable of a working pressure of 16 bar or 25 bar depending on the flange arrangement, and are all hydrostatically tested upon assembly to 24 bar or 37.5 bar respectfully. These pumps are designed for 40 bar working pressure.

Mechanical seal
Carbon/Ceramic/EP single seal or Carbon/Silicon Carbide/EP single seal depending on the number of stages.
Drivers
Pumps are generally supplied  with a 3 phase electric motor. Single phase motors are available up to 2.2 kW. Alternative motor makes and specifications are readily available, including pump and motor combinations for 60 hz operation.

Materials
All parts of the pump coming into contact with the pumped liquid are of stainless steel.

Impellers, diffusers and sleeve:                304 SS
Shafts                                303 SS
Bushes and spacers                        303 SS
Base plate and motor adaptor:                Cast iron
O ring gaskets                        EP rubber

Pumps are also available in 316 stainless steel.
