Stwin screw pump with Servo Motor

Applications

Twin screw pump has strong self priming ablity, can transport solid particles, gas liquid mixture, high viscosity, low viscosity and other materials. The pump not only can extract and convey materials, but also apply for CIP and SIP systems, can reduce pipeline, valve and CIP exclusive pumps, which improve efficiency and save cost, It has extra characteristics, that other volume pump do not have, such as no pulse phenomenon, no particle damage, high pressure, wide speed range, large flow range and so on.
And used for complex working condition or material transportation and extraction with high-efficiency self-priming ability and transportable solid particles,gas-liquid mixture,high viscosity,low viscosity,etc.

Specifications

Twin Screw pump mechanical seal Design

1. Single mechanical seal

2.Double mechanical seal

Materials : SIC/SIC/EPD, SIC/C/FKM, SIC/C/HNBR ,SIC/SIC/EPDM, SIC/SIC/FKM, SIC/SICHNBR, TC/TC/EPDM, TC/TC/FKM, TC/TC/ HNBR

Twin screw pump for CIP Cleaning and media delivery configuration

With its strong self priming capacity , the LG series screw pump have the alibity to deliver high viscosity and low viscosity medium, as well as cip liuqid extraction and cleaning functions. Choosing LG Serices screw pump will help you to reduce using cip dedicated pump and valve control system, it will save cost .

Design
1. material transportation and extraction
2. apply for CIP and SIP systems
3. no pulse phenomenon, no particle damage
4. high pressure, speed range, larage flow range and so on

Flexible soluction for two Direction reversible, High pressure, High Viscosity, Large Particle, Pulse free, Liquid Delivery.

Choose the right screw spacing for your process

Option 1: Large screw spacing, large flow rate, Can deliver larger particles, But the pressure will be lower compared with samll spacing screw

Option 2: Samll Screw spacing, lower flow rate but higher pressure, the particles that can be transported will also be smaller.
