Flexible Impeller

Our Flexible Impeller Pumps with high-quality rubber impellers & housed vanes, effortlessly handles thin, viscous & shear-sensitive fluids and solids in suspension, ensuring suitability for emptying sumps, tanks, drums & IBCs. Simple construction & few moving parts, pulsation-free flow, and ATEX availability for use in hazardous environments.

What is a Flexible Impeller Pump?

Flexible Impeller Pumps are characterised by their unique construction and impressive technical specifications. These pumps, also known as Flexible Vane Pumps, feature an impeller made from high-quality rubber, complemented by vanes housed within the pump. This design feature means the pump can effortlessly handle thin and viscous fluids, and solids in suspension. The simple construction features only a few moving parts which in turn reduces downtime thanks to the simple maintenance requirements.

What are your Fluid & Media Transfer Characteristics?

To choose the appropriate Flexible Impeller Pump for your application, ask yourself the following questions:

What media will be pumped? Consider the chemical composition of the media you will be pumping – is it chemically neutral or corrosive, shear sensitive etc.
What is the viscosity of the media you intend to pump? Consider viscosity limitations, shear sensitivity etc.
Do you need to pump fluids containing solids?
Is your environment or fluid explosive?
Do you require CIP/SIP?
Do you require self-priming capabilities

Impeller Materials Available

NBR: Excellent resistance to Oils & fats, FDA-approved
CR: Ideal for chemical and mechanical resistance
EPDM: Used for hot liquids and CIP, FDA-approved, ideal for acids and alkalis
NR: Best mechanical resistance, ideal for room temperature water-based fluids
VMQ: Used for high temperatures with low mechanical resistance

Some of our materials offer an ATEX option on request for explosive applications and environments.

Maintenance Required to Keep your Flexible Impeller Pumps Running

Visual inspections of the casing, impellers and vanes to check for signs of leaks or damage
Ensure proper alignment of the shaft
Ensure the shaft seals and gaskets are replaced if worn or damaged
Grease/lubricate bearings and shafts
Inspect electrical wirings and connections for signs of damage
Ensure flows and pressures are accurate
Listen for excessive noise as this could indicate a mechanical issue

Depending on the size of your pump and the fluid you are pumping, a more detailed maintenance schedule may be required.

Additional Factors to Consider

Will your pump be stationary, or do you need it to be portable? If you require portability, Flexible Impeller Pumps can be fitted to trolleys of any size to suit your needs.
