Double screw pump:

What is a screw pump? Screw pumps belong to the positive displacement pump principle, using one or more screws to move fluids or solids along the screw axis. Historically, the pump was invented by Archimedes to transport water from the fields to higher water levels. Today, we use this pump in many hygiene applications such as food, dairy, beverage, cosmetic, pharmaceutical and chemical applications.

How the double screw pump works:

The twin screw pump is a positive displacement pump, which means that the pump delivers a certain volume of product according to the speed and pitch of the screw. When rotated, the two screws form a closed chamber that moves axially. This motion creates a vacuum on the inlet side and a pressure on the outlet side. Thanks to this two-chamber technology, there is almost no pulsation when handling high and low viscosity products.

Why choose double screw pump:

A major feature of twin-screw pumps is that they can operate over a wide range of speeds. With this feature, these pumps can have dual functions in sanitary applications, pumping products at low speeds and CIP fluids at high speeds, so there is no need for additional CIP pumps. By design, twin-screw pumps provide pulsation-free flow for low-viscosity products (<1cP), volatile and gaseous fluids. In addition, because of their design, these pumps are capable of producing a high vacuum, which allows the pump to self-priming. JEC twin-screw pumps have been developed according to the highest hygiene specifications such as EHEDG and 3A to meet the highest hygiene and efficiency requirements for the most refined hygiene applications!

Application of double screw pump:

• Pump structure sensitive products

• Pump fluids containing solids

• Multiple use, low capacity operation at low RPM and high RPM for CIP cleaning

• Suitable for applications where high viscosity and low viscosity products need to be pumped under high pressure.

• Applications requiring pulsation-free flow

Advantages of double screw pump:

• Flexible for optimal operation in a wide range of conditions: from high viscosity liquids to low viscosity liquids

2-in-1 pump: High-speed rotation range (up to 3,000rpm) ensures "2-in-1" operation of the product and CIP.

• No pulsation for gentle handling and high suction performance

• The outer gasket between the gearbox and the housing reduces a lot of time-consuming rotor alignment.

• Approved by 3-A and EHEDG, elastomers comply with FDA and EC1935/2004 standards.

• The integrated gear adapter can be directly coupled to the B5 and 4-pole motors.

• Simple and easy maintenance, low service cost.

• Fully drainable front cover.
