Faqs

What are rotary piston pumps used for?

Rotary piston pumps are used for handling of high-viscosity fluids, including oils, resins, and fuels. They are ideal for applications requiring self-priming and reversible flow capabilities.

What are the benefits of using rotary piston pumps?

High Viscosity Handling: Can manage fluids up to 200,000 cst. High Temperature Tolerance: Operates efficiently up to 300°C. Self-Priming: Suitable for suction lift operation. Reversible Flow: Enables flexible fluid transfer.

Rotary Piston Pumps: Versatile Fluid Handling for High Viscosities

Rotary piston pumps are a type of self-priming, reversible positive displacement pump designed to efficiently handle high-volume, viscous fluids like oils, resins, and fuels. Engineered to manage fluids with viscosities up to 20,000 cSt and temperatures as high as 300°C, these pumps are ideal for industries where handling thick or high-temperature fluids is critical.

The rotary piston pump operates with a unique design, featuring a piston that slides back and forth along a rotor's groove. As the rotor spins, it acts as a rotary valve, pulling fluid into the pump's inlet and enabling the pump to self-prime effectively. Two direct-driven pistons work in twin cylinders: one piston moves toward the centre of the pump near the inlet, and the other moves towards the outlet, expelling the fluid.

This efficient configuration allows rotary piston pumps to handle a broad range of high-viscosity fluids with precision and reliability. Their self-priming and reversible operation make them incredibly versatile, suitable for fluid transfer and circulation tasks across various industries, including oil and gas, chemicals, and manufacturing.

By utilising the rotary piston design, these pumps provide a dependable and efficient solution for managing challenging, high-viscosity fluids in applications that require precise, high-volume fluid handling. Whether used in heavy industrial processes, chemical transfer, or high-temperature systems, rotary piston pumps ensure optimal performance and reliability in demanding environments.
