FAQs

How does a Hydraulically Driven Flexible Impeller Pump work?

Like other Flexible Impeller Pumps, this operates by the rotation of the internal shaft, which causes the flexible impeller to bend against the casing, pushing fluids and solids out of the discharge port.

How does this differ from other products on the Tapflo website?

The bare shaft allows the user to supply their own motor to the pump. This is ideal when an existing transmission system is already in place such as a PTOs, belt drives or hydraulic motors on vehicles.

What is the difference between a Centrifugal and a Flexible Impeller Pump?

A Centrifugal Pump is a Rotodynamic pump that passes energy from the motor to the liquid, which forces the fluid out of the discharge port. Whereas the Impeller Pump is a Positive Displacement Pump that traps small amounts of liquid and forces it from the suction to the discharge port.

What applications are suited to this pump?

This pump is suitable for the food & beverage industry with pumping liquids and pulp products. Industrial applications such as oils and paints. Agricultural applications such as low head transfer and emptying tanks, sumps and containers. The Marine industry with applications such as tank-to-tank seawater transfer, sludge and slurries. Transportation applications such as loading and offloading of products, and hygiene applications such as filling and emptying containers.

Is this pump suitable for abrasive or hazardous chemicals?

Suitability depends on the application and material selection. The impellers are available in Natural Rubber, Neoprene, NBR, EPDM and Silicone, which offer differing levels of chemical resistance and durability.

Bare Shaft & Hydraulically Driven Flexible Impeller Pump

Tapflo UK is proud to be a partner of Liverani, a leading Italian manufacturer, supplying us with highest-quality Flexible Impeller Pumps and Liquid Ring Pumps.

The S/P and MID ranges of Flexible Impeller Pumps, are designed to deliver pulsation-free pumping for the Agricultural and Transportation industries. With solids passage up to 25mm (range dependant) and self-priming capabilities up to 6m from dry, ensuring superior suction lift capacity for a range of applications. The Bareshaft S/P range connects via PTO or coupling and is available in 4 sizes, while the MID Hydraulically Driven range suits hydraulic motors or couplings and is available in 3 different sizes. With the flexibility to rotate the pump head into 5 different positions, and a variety of impeller materials options, these pumps deliver optimal performance in both the Industrial and Hygienic sectors.

Typical applications for our S/P & MID Flexible Impeller Pumps:

  • Loading and offloading
  • Emptying of tanks, sumps and additional containers
  • Adaptable for vehicles such as trucks, tractors, and boats
Overview

Bareshaft S/P Range

The Bareshaft S/P Series of Flexible Impeller Pumps are available in 4 different sizes (MINI, MINOR, MAJOR and MAXI).

The series can be connected with a PTO drive or can be assembled to an existing motor and baseplate via a coupling.

MID Hydraulically Driven Range

The MID Series is available in 3 different sizes, MINOR, MAJOR and MAXI. These Flexible Impeller Pumps can be fitted with Orbital Hydraulic Motors (50 CC) or with coupling suitable for attachment to an existing hydraulic drive system.

Manual & Spring Loaded By-Passes are available on request.

In general, Self-Priming Flexible Impeller Pumps are often used for applications where the process media is delicate, shear sensitive or viscous with solids in suspension.

The Bareshaft and Hydraulically Driven Flexible Impeller Pump Series’ is particularly useful when an existing drive train is already in place such as a PTOs, belt drives or hydraulic motors on vehicles such as trucks, tractors and boats.

The S/P and MID Series’ are the perfect solution for low head transfer, filling, metering, loading and offloading applications in both industrial and hygienic sectors for a variety of reasons, including:

  • Lightweight and compact design
  • Versatile port configuration
  • Ability to handle a wide variety of fluids
  • Range of accessories available to create the right solution for your application
