The PPS plastic vertical pump range is efficient, heavy duty and reliable at a competitive price. Not only is the PPS rigid and vibration free, but it's capable of being installed for many years of trouble free service in sump emptying applications with column lengths from 1 - 4.5m.

External Flushing Available
Flexible To Your Design Requirements

The wetted parts are fully corrosion resistant and machined from solid plastics. The PPS range features suspension systems with integral stiffening bars to prevent longitudinal movement. A feature of the PPS range is the ability to adjust the impeller gap from above the mounting plate, without having to remove the pump from the sump or tank.

The stabilising PTFE and high alumina ceramic bearings are usually product lubricated, however, for liquids, which contain a high degree of solids or abrasives, external flushing lines can easily be fitted. 

The impeller can be either semi-open or fully closed depending upon the type of application. Radial back-vanes machined on the impeller ensure a continuous and plentiful flow to lubricate the bottom slide bearing.

Designed and manufactured in the UK means we can tailor the pump to your specifications within competitive lead times.

Efficient & Heavy Duty

The PPS range offers a reliable, efficient, and long-lasting pumping solution while reducing maintenance requirements.

But selecting the right pump goes beyond just initial cost—energy and maintenance make up the majority of a pump’s lifetime expenses. With our Life Cycle Cost (LCC) calculator, you can compare different pump options and see the true cost of ownership, helping you make the most efficient and cost-effective choice.

Frequently Asked Questions

What is the difference between submersible and immersible pumps?

Submersible pumps are complete units, including the motor, and the whole can be totally submerged whereas immersible pumps are mounted in vertical position with the motor above the liquid and the pump end extended below the liquid level.

How does a vertical immersible pump work?

A vertical immersible pump operates with its pump end submerged in the fluid while the motor remains above the liquid level. The pump uses an impeller to draw fluid up through the pump column and discharge it at the surface. This design prevents motor exposure to harsh fluids, making it ideal for handling corrosive, abrasive, or high-temperature liquids in industries like chemical processing and wastewater treatment.

What Are the Advantages of Using a Vertical Immersible Pump?

Vertical immersible pumps offer several benefits, including space-saving design, as they require a smaller footprint than horizontal pumps. They prevent motor exposure to corrosive or hazardous fluids by keeping the motor above the liquid level. These pumps also provide high efficiency and reliability, with minimal risk

of leaks due to their seal-less or semi-sealed designs. Additionally, they are easy to maintain, as the motor and key components remain accessible without needing to drain the tank or sump
