Progressing cavity pump unit B70V-D

for food productswith electric motorself-priming

Description
The eccentric screw pump unit B70V-D in PURE design is a positive-displacement pump for medium to high viscosity and highly viscous media up to the limits of flowability. Depending on the application, different three-phase motors are available and can be combined with the pump unit at any time to ensure operational flexibility and resource efficiency.

• also available in special immersion depths
• example media: viscous cosmetic products, food products, etc.

Features & Benefits

• Consistent volumetric flow
• Easy and fast cleaning
• Gentle, low-pulsation product transfer
• Quiet operation and low wear
• Wide range of robust, high-performance drive motors
• Approved according to ATEX Directive 2014/34/EU, Category 1/2
