Plenty Mirrlees Pumps have been manufacturing Rotary Positive Displacement Pumps for Refinery services for more than 50 years, manufacturing three series of Rotary Positive Displacement Pumps, that perform well when utilised on Refineries.

Twin Screw Pumps 

Twin Screw Pumps are primarily designed for bulk liquid transfer and processing applications involving low viscosity products. The principal design feature is that no metallic contact takes place between the screws or between the screws and their bores, which enables the pumps to handle a wide range of fluids, including those with no lubricating properties. 

Twin Screw Pumps

A significant feature of TWINRO pumps is their self-priming high lift capability, enabling them to displace large volumes of air and gas from long suction lines. 

Sliding Vane Pumps 

Although a Sliding Vane Pump does not readily spring to mind when talking about Refinery Applications, the Plenty range of pumps are unique. Unlike conventional Sliding Vane Pumps, the Plenty Vane Pump works on a different patented principle. 

The addition of a rotating ring (Rotor) to the pumping element, enables the Plenty design to utilise a much stronger Vane section. This Heavy-Duty design gives a very adaptable pump that can be used for many different refinery applications on a diverse range of liquids. The standard factory pump is suitable for handling viscosities up to 75,000 cSt. 

Sliding Vane Pumps - Variable Capacity 

The patented Plenty Vane Pump also has the unique capability to deliver an infinitely variable flow rate from full capacity all the way down to zero, and without any form of spillback. These pumps can be supplied with devices to enable the pump flow rate to be varied either by Remote Control, Manual Adjustment or even to match process conditions Automatically using our patented CPC (Constant Pressure Control) mechanism. 

Triple Screw Pumps 

Triple Screw Pumps are generally utilised on Refineries for applications such as Forced Lubrication in Lube Oil Systems associated with other on-site rotating machines such as Gearboxes, Engines and Turbines etc. and Seal Oil Circulation on Compressor systems. 

The TRIRO Triple Screw Pump has only three moving parts - a power rotor and two idler rotors. Triple Screw pumps are designed principally to pump clean lubricating liquids, and are suitable for operation at high pressure. The three rotors are accurately machined and intermeshed to give a smooth pulse free flow and exceptionally quiet pump operation.
