TWIN SCREW PUMPS
Twin screw pumps offer smooth, low-shear handling of viscous and shear-sensitive products across food, dairy, beverage, cosmetic, and pharmaceutical processes. With precise rotor geometry and robust stainless steel construction, they deliver consistent, pulsation-free flow even under challenging conditions. Many models can also be sized to accommodate CIP flow, allowing a single pump to handle both process and cleaning duties, reducing system complexity and cost. Alliance Fluid Handling holds UK stock of both complete pumps and spare parts, ensuring fast supply and minimal downtime for your process.
TWIN SCREW PUMP MAKES & MODELS
CSF PUMPS
TS SERIES

Hygienic double-screw pump can run at low or high speeds, ideal for both process flow and CIP duties; excellent suction with low NPSHr and nearly pulsation-free operation (no foaming even with gas entrainment); available in standard and TSM close-coupled versions for flexible installation.
Benefits
One pump handles production and CIP cleaning (reducing system complexity); gentle on delicate or solid-containing fluids (no product damage or shear); high volumetric efficiency with no product contamination or wear particle transfer for reliable sanitary operation.
Applications:
Food & beverage, dairy, cosmetic and pharmaceutical fluids (e.g. juices, purees, syrups, soups, milk, creams, shampoos).
Certifications:
Designed to meet EHEDG and 3A standards (certified execution available)
Downloads:
Flow Rates: 0.1–230 m³/h
Pressure: Up to 25 bar (16 bar typical)

SLH 4G
Features:
Modular three-part casing with customizable ports and heating jacket options; aseptic design version available (EHEDG EL Class I Aseptic); non-contact, self-priming twin-screw operation (same dual-duty principle as SLH-4U).
Benefits
Premium design offers aseptic processing and tailored configurations; maintains gentle, low-shear pumping for high product integrity; provides low-pulsation, dual-duty performance with added flexibility for special applications.
Applications:
All hygienic applications as SLH-4U (food, dairy, beverage, pharma, cosmetics), plus aseptic processing needs.
