Twin Screw Pumps

Twin Screw Pumps efficiently transfer a specific volume of fluid based on the screws’ speed and pitch. This pump’s unique design features two screws that create closed chambers that move axially, generating a vacuum at the suction point and pressure at the discharge point. This double-chamber design provides smooth, low-pulsation flow for both high- and low-viscosity fluids.

Our pumps meet the highest industry standards, with EHEDG- and 3A-compliant designs for enhanced sanitation. Some key benefits of using Twin Screw Pumps are:

• EHEDG- and 3A-compliant
• Support CIP/SIP functions
• Non-contacting running screws that exhibit remarkable wear resistance
• Enhanced durability and reduced maintenance requirements
• Low pulsation characteristics
• Wear-resistant mechanical seals
• Exceptional priming capabilities
• Low NPSH values to mitigate cavitation risks
• Handles low- and high-viscosity fluids, including those entrained with air
• Supports suction, feeding, filling, supply, flushing, dosing, loading, and offloading applications
• Well-suited to handling solids
• Multiple sealing options available, including lip seals and single or double mechanical seals
• ATEX-approved options available for hazardous environments

Common applications and industries include:

• Food & Beverage
• Cosmetics
• Pharmaceutical
• Chemical

To choose the appropriate Twin Screw Pump for your application, ask yourself the following questions:

• What media will be pumped? Consider the chemical composition of the media you will be pumping – is it chemically neutral or corrosive, shear sensitive etc.
• What is the viscosity of the media you intend to pump? Consider viscosity limitations, shear sensitivity etc.
• Do you need to pump fluids containing solids?
• Is your environment or fluid explosive?
• Do you require CIP/SIP?
• Do you require self-priming capabilities?
• Will your pump be stationary, or do you need it to be portable?

Twin Screw Pump body is constructed mostly from Stainless Steel AISI 316 & 630, which provide excellent corrosion resistance

Some things that can help your pump perform in good working order are:

• Visual inspections of the pump’s components to spot any wear or damage
• Check the pump’s noise levels; excessive noise may indicate wear problems to gears and bearings, dragging of screws on the pump casing, or cavitation
• If a flushing system is present, check the pressure and flow
• If a heating/cooling system is present, ensure temperature capabilities are at optimal levels
• Oil level in the gearbox

Depending on the size of your pump and the fluid you are pumping, a more detailed maintenance schedule may be required.
