What is the BO/SO progressing cavity pump?
The NEMO® BO/SO progressing cavity pump with hopper and coupling rod with feeding screw and force-feed chamber is employed in almost all branches of industry to provide continuous, pressure-stable, gentle and low-pulsation conveyance. The hopper housing with cutting unit guarantees optimum feed of chunky medium into the conveying elements. If the medium passes the force-feed chamber with the cutting unit the larger fruits and vegetables are cutted immediately. This unit consists of a rotating knife with three blades and a variable number of stationary knives adjustable to the size and consistency of the particles.
Feeding through Hopper with Cutting Unit
The hopper housing with cutting unit guarantees optimum feed of chunky medium into the conveying elements. If the medium passes the force-feed chamber with the cutting unit the larger fruits and vegetables are cutted immediately. This unit consists of a rotating knife with three blades and a variable number of stationary knives adjustable to the size and consistency of the particles.
Optionally the pump can be equipped with an additional cutting unit at the discharge flange of the pump. With its perforated disc and rotating knife it allows for further fine definition of the particle size.
As any other NEMO pump also the BO/SO pump has the ability to dose the conveyed media in proportion to rotation speed. In block construction with a flanged drive, this pump is particularly compact and economical. It is also available with bearing housing for a wider range of drives.
Features of the pump
- Hopper housing with rectangular inlet flange and feeding screw with force-feed chamber to provide optimal feed for slowly flowing and pasty media into the conveying elements
- Continuous low-pulsation conveyance una ected by fluctuations in pressure and viscosity
- Conveyance volume in proportion to rotation speed with high dosing precision over a broad rotational-speed range
- High pressure capability without valves
The Advantage of NEMO® BO/SO Hopper Pump
- Variable modular system for optimum conveyance and cutting
- Robust and compact construction
- Constant flow
- Ease of service
- Replacing additional machinery
