PLP Sanitary Lobe Pump is available with several, interchangeable, shaft sealing options. They are modularly built and are front pull-out by design making replacement and re-assembly very quick and easy. The type of sealing is dependent on the application requirements and can be supplied in the following variants & material combinations:
Materials: Silicon Carbide/Silicon Carbide and Tungsten Carbide/Tungsten Carbide sliding rings Elastomers: NBR, EPDM, Viton, PTFE, Kalrez
The PLP Sanitary Lobe Pumps can be fitted with either Spring-Loaded or Air Operated Safety Relief Valves. The opening pressures of which are adjustable by means of a set screw. The valve is mounted directly to the pump cover to facilitate easy maintenance and to guarantee optimal hygienic conditions. When the valve is opened a by-pass is created between the pressure and suction sides of the pump. When the differential pressure within the pump head exceeds the pre-set value on the valve, the valve will open and protect the pump from the deadheading. Below is a table detailing the models of pumps which can be fitted with either type:
| Safety Relief Valve Type | PLP 1-¾ PLP 1-1 PLP 1-1.5 | PLP 1.5-2 | PLP 2-1.5 PLP 2-2 PLP 2-2.5 | PLP 3-2 PLP 3-3 PLP 3-4 | PLP 4-4 |
| Spring Loaded | X | X | X | X | |
| Air Operated | X |
PLP Lobe Pumps can be fitted with Heating / Cooling Jackets to maintain fluid temperatures which are optimal to the pump performance and system requirements. These are supplied in the following variants:
Depending on what size of PLP Lobe Pumps you have on-site, some models have common spares, detailed in the following tables, which can vastly reduce the number of different spares that are required on-site.

The PLP Sanitary Lobe Pump is a Rotary Positive Displacement Pump. Its operation is based on the counter-rotation of 2 lobes in the pump casing. Both lobes are mounted onto their own shafts which are supported by bearing cartridges mounted directly onto the pump casing. One of the pump shafts is externally driven and an internal gear assembly drives the other shaft in the opposing direction. The screws rotate synchronously in opposing directions without touching.
When the lobes rotate and pass the suction port the volume between them increases and create a vacuum which causes the liquid to enter the suction port and the pump casing. During the rotation of the lobes, a fixed amount of fluid is conveyed through the pump. As the lobes approach the discharge port the volume between them decreases which creates a pressure build-up, causing the fluid to flow out of the discharge port.
