Flexible impeller pumps

Flexible impeller pumps are rotary or positive displacement pumps that transfer products such as water, high viscosity liquids, or abrasives and corrosives fluids. They offer great wear resistance and excellent performance even with solid particles

Whether for bilge drainage, deck washing, toilet water or general purpose, flexible impeller pumps combine the advantages of rapid self-priming, the ability to handle water containing solid matter and built-in protection against dry-running where pumps need to be reliable, efficient and easy to use

  • Available in steel, stainless steel and bronze

  • Impellers in nitrile,  neoprene, non-toxic, high pressure, EPDM, ...

  • Flow capacities up to  30 m³/h

  • Operating pressure range up to 5 bar

  • Available in a range of AC and DC voltages

  • Applications in general industry

  • Marine applications

  • Transfer and circulation of fresh and salt water

Flexible impeller pump  Oil and Diesel Line

Corrosion resistant bronze body, stainless steel shaft

Sliding-vane pumps are purpose-designed to handle diesel fuel, gas oil, kerosene and paraffin rapidly and efficiently, delivering high flow rates with minimal battery drain. Positive sliding-vane action ensures quick self-priming from dry. Unlike a centrifugal pump, a sliding-vane pump clears most of the residual fuel from the hose when the supply vessel is empty

  • Power supply: 12 Vdc, 24 Vdc, 240 Vdc

  • Sizes ranging from 1/4" to 2 1/2"

  • Capacities up to 480 L/min

  • Connections: BSG threaded ports, hose

  • Temperature range 70ºC to 80ºC

  • Viscosity up to 1,000 cSt

  • Transfer of different types of fuels

  • Lubricating oil-change

  • Engine oil drain

Flexible Impeller pump  Engine Cooling Line

These pumps are available in a wide variety of typesand sizes to meet the needs of different refrigeration systems. Flanged pumps that mount directly to the engine on a power take-off, pumps to be installed on the crankshaft pulley and pulley-driven pedestal pumps

  • Sizes ranging from 1/4" to 2"

  • Capacities up to 300 L/min

  • Different types of connections: Flanges, BSP

  • Materials: Bronze, staniless AISI 304 or stainless steel AISI 316

  • Impeller: neoprene or nitrile

  • Marine engine cooling

  • Protection of nozzles and heat exchangers

  • Pre-filtration in water treatment facilities

  • Industries such as metal production, food processing, pulp and paper, chemicals, and oil and gas

Working principle

Flexible vanes create increased volume when leaving the eccentric cam creating a vacuum, and thus drawing in liquid, instantly priming the pump

As the flexible vanes rotate, the liquid is carried through the pump from the inlet to outlet port, each successive vane drawing in liquid

When the flexible vanes again contact the eccentric cam they bend with a squeezing action which provides a continuous, uniform discharge of liquid
