Hopper progressive cavity pump in block construction
What is the open hopper feed progressive cavity pump in block construction?
The open hopper progressive cavity pump in block construction is a kind of direct-coupled progressing cavity pump, its hopper is usually square or rectangular, because it has coupling rod with auger and force-feed chamber, so it can tansport some materials with high viscosity and poor fluidity with continuous, pressure-stable, gentle and low-pulsation.

The feature of the open hopper cavity pump
- Open hopper pump is sction hopper with rectangular mouth (with / without auxiliary feeding chamber)
- coupling rod with feeding blade can force medium into the closed conveying chamber between rotor and stator
- The size of rectangular hopper can be adjusted according to the actual needs
- The flange is directly connected, and the structure is simple
- Low cost of investment, use and maintenance
- The flow is proportional to the speed
- Used for continuous, pressure stable, stable and low pulsation transportation
- Professional transport of low mobility or even non mobility of high viscosity, high solid content media
