Ace rotary lobe pump for sale

This sanitary lobe pump is ideal for handling all types of fluids, whether low or high viscosity, as well as filtering and filling applications. Products containing fragile solids such as curd can be pumped without damage thanks to the specially designed lobes.

How does a lobe pump work?

There are 2 lobes inside the pump casing that rotate in opposite directions without touching each other. As the lobes rotate past the suction port of the pump casing, the volume between the lobes increases, creating a vacuum which draws liquid into the pump casing. 

As the vanes rotate towards the discharge port, pressure builds up as the volume between the vanes decreases. 

This causes the liquid in the pump casing to flow out of the discharge port, as shown in the diagram.

Advantages of using a lobe pump

1. The lobe pumps supplied by Ace are fully HEDGE compliant and are manufactured from stainless steel to ensure the pumps are hygienic.

2. Lobe pumps can be installed horizontally or vertically in pipework, demonstrating their versatility. When installed vertically in the pipework, the pump can be self draining, which is particularly useful alongside the SIP & CIP feature of a lobe pump.

3. The mechanical seal and lobes of the pump can be completely removed from the front of the pump casing, making maintenance of a lobe pump easier.

4. Lobe Pumps have an accurate flow control range, can be fitted with a variety of connection types, heating or cooling jackets, integral air or spring-loaded safety valves and the option of Bi-Wing Lobe or Quarto Lobe design.

These variations can all be fitted depending on the application you want to use a lobe pump for, let us know what you need and we'll specify the pump for you.

• If the oil level has dropped, check the pump for oil leaks.

• The suction and discharge pressures of the pump, ensure they are at standard system levels.

• If your lobe pump is fitted with a heating or cooling jacket, check that the temperature is correct.The pressure and flow of the flushing system, if your pump has one.

• When to change the oil in your lobe pump

• After 300 hours of operation since the pump was first put into service, the oil should be changed.

• After the initial oil change, your pump should be changed every 3000 hours of operation or every 3 months, whichever comes first.
