SSG PROGRESSIVE CAVITY SINGLE SCREW PUMP

SSG Progressive Cavity Single Screw Pump

MODEL: SSG

SSG Progressive Cavity Pump is a positive displacement, single screw pumping solution engineered for the reliable, stable & high accuracy transfer of liquids with varying viscosity, solids content and shear sensitivity. Using a helical rotor operating within a resilient stator, the pump generates continuous, low-pulsation flow with precise volumetric accuracy. This unique design enables high suction performance, consistent pressure output, and gentle media handling, making it ideal for industrial applications ranging from lubricants, polymers, fuels, and chemicals to food products, wastewater, and process slurries. Designed for efficiency, durability, and seamless integration into automated systems, the SPEW SSG delivers stable performance where conventional pumping technologies fall short.

Features

Smooth, Pulsation-Free Flow
Progressive cavities provide continuous, non-pulsating discharge that protects downstream instruments and ensures accurate process control.
Handles Wide Viscosity Range
Capable of pumping everything from thin solvents to highly viscous oils, polymers, sludges and pastes without loss of performance.
Self-Priming & High Suction Capability
Strong suction performance and low NPSH requirements enable reliable operation in difficult suction conditions and tank stripping duties.
Low Shear, Gentle Product Handling
Ideal for shear-sensitive products such as emulsions, food ingredients, additives and specialty chemicals.
Accurate, Speed-Proportional Flow
Flow rate is directly proportional to pump speed, allowing precise dosing and metering when combined with VFD or PLC control.
Solid-Handling Capability
Can handle soft solids and particulate-laden media without significant loss of capacity.
Flexible Materials & Configurations
Multiple rotor materials and stator elastomers (NBR, EPDM, FKM, HNBR, PTFE, food-grade) plus horizontal, vertical and hopper-type designs.
Easy Maintenance & Long Service Life
Modular design with accessible stator/rotor, standard mechanical seals and robust bearings for reduced downtime and lower life-cycle cost.
Automation Ready
Fully compatible with VFD, PLC, SCADA and DCS systems using standard electrical and instrumentation interfaces.

Structures

The SPEW Progressive Cavity Single Screw Pump is built around a simple, robust mechanical structure designed for heavy-duty industrial service:

Rotor
Precision-machined single-helix rotor in hardened steel, stainless steel or duplex alloys, with optional surface treatments for abrasion and corrosion resistance.
Stator
Molded elastomer stator (NBR, EPDM, FKM, HNBR, PTFE, etc.) forming double-helix cavities with the rotor to generate the characteristic progressive displacement.
Suction & Discharge Casing
Rigid casing in cast iron, carbon steel or stainless steel with standardized DIN/ANSI flanged connections; optional jacketed versions for heated products.
Drive Train
Torsionally rigid coupling connects the rotor to a helical gear reducer and electric motor. Configurations include direct-coupled, baseplate-mounted and skid-mounted assemblies with optional safety coupling guard.
Bearing & Seal Arrangement
Heavy-duty bearings (where applicable) support axial and radial loads; sealing options include single or double mechanical seals and gland packing for challenging services.
Baseframe / Skid
Fabricated steel base or skid provides precise alignment of pump, gearbox and motor and simplifies transport, installation and maintenance.
