Unibloc® Twin Screw Hygienic Pumps

Game-Changing External Timing Adjustment

Unibloc® Twin Screw positive displacement (PD) pumps redefine what’s possible in high-pressure hygienic applications. While other pumps require disassembly for timing adjustments, our externally adjustable timing system enables precision adjustments in just five minutes. No disassembly, no contamination risk from opening oil-filled housings on the production line, no downtime.

Foolproof One-Way Screw Reassembly

The new Unibloc Twin Screw pump features an innovative design that ensures perfect alignment every time, eliminating guesswork during assembly. With identical drive and lay screws, reassembly is simpler and spare parts inventory is streamlined, reducing complexity across maintenance operations. This design allows technicians to get reassembly right on the first try—without rework.

Ultra-Hygienic Design

Our seamless design features shafts and housing milled from a single billet of stainless steel, eliminating seams that could harbor bacteria. Fewer parts than competing screw pumps reduce the risk of foreign object contamination, while our advanced oil reservoir design delivers optimal flow and circulation for superior heat dissipation and extended bearing life.

High-Performance Applications

• Delivers the highest discharge pressure of any hygienic pump.
• Handles viscous products up to 1,000,000 cP.
• Ideal for shear-sensitive products with entrained solids up to 45mm.
• Minimize waste with High RPM enables effective Clean-In-Place (CIP) with reversible operation.
• The family of four pumps has flow capacities from 110 to 880 gallons (416 to 3333 liters) per minute with volumetric efficiency greater than 90%.
• The pumps can operate at temperatures up to 392° F (200 °C) and at system pressures of 360 psi (24.8 bar) to enable their use with a wide range of products.
• Operating speeds up to 3600 RPM for increased productivity.
• Like other UHT pumps, pump housings and screws are milled from a single stainless-steel billet, eliminating seams that trap product and bacteria.

Benefits

• Advanced design and fewer parts lead to easier, simpler, faster maintenance.
• External access to timing adjustments – without having to open messy oil-filled housings.
• Preserves the integrity of shear-sensitive, high-viscosity products, handling everything from small-batch specialty products to high-volume production runs.
• Smooth, consistent non-pulsating flow even at high flow rates.
• Dual-duty design — a single pump for processing at low speeds or effective CIP at higher speeds.
