Twin Screw Pumps

Hygienic twin screw pumps combine process flexibility with high hygienic standards. They are ideal where cleanability, gentle product handling and wide operating windows are required. Each pump is configured to the application, so complete pump part numbers are not listed.

Overview

Twin screw technology is widely used in hygienic processes where the same pump must handle varying flow, viscosity and operating conditions. The pump range is engineered for applications in dairy, beverage and food processing where cleanability is critical.

Design & Reliability

  • Front-loading cartridge shaft seal for quick service.
  • Rigid stainless steel gearbox with timing gears located between bearings for balanced loading.
  • Oil chamber design with enhanced lubrication to bearings and gears.
  • Service-kit option available for cost-effective seal wear-part replacement.

Hygienic Standards

  • Designed for high cleanability in hygienic applications.
  • EHEDG certified and conforms to 3-A sanitary standards.
  • Suitable for CIP/SIP-focused environments (depending on configuration).
  • Optimized for industries where hygiene and product integrity matter.

Pump Range

The twin screw pump family is available in nine models based on three frame sizes. Each frame size is offered with three screw profiles to match pressure, flow and solids handling requirements. Because pumps are customer-configured, we specify the final configuration based on your process data.

Frame Sizes & Profiles (Overview)

  • 3 frame sizes (selection depends on duty point and installation constraints).
  • 3 screw profiles per frame (optimized for pressure, flow and solids handling).
  • 9 models total across the full range.
  • Seal options: assembled cartridge seals or service-kit approach for wear parts.
* We provide final model/profile recommendation after reviewing your product and performance data.

FAQ

Quick answers for common twin screw pump questions.

Why are there no complete pump part numbers listed?

Twin screw pumps are typically configured per application. The final model, frame size, screw profile, seals and connections are selected based on your product and performance data.

What makes twin screw pumps suitable for hygienic processes?

Hygienic twin screw pumps are designed for high cleanability and are commonly chosen for sanitary industries where CIP/SIP performance and product integrity are priorities.

How do screw profiles affect performance?

Different screw profiles are used to match required pressure, flow and solids handling capability. After receiving your duty point and fluid data, we propose the best profile for your process.
