Sanitary Progressive Cavity Pumps
The Progressive Cavity Pump belongs to the positive displacement pumps family.
The working principle is based on the volumetric displacement of the pumped products by the main pump elements, a metal rotor rotating within a static elastomeric stator.
This principle is well suited to pumping viscous to semi-abrasive liquids, including solids in suspension. PC pumps deliver a smooth flow, which can be varied in proportion to the speed of the drive motor. Benefits include self-priming and the ability to operate flexibly at both low and high rotational speeds, while maintaining a high volumetric efficiency.
PC pumps are renowned for their versatility in handling a wide range of different media.
To facilitate this the range of accessories includes various different pre-feeding hoppers and augers for viscous liquids.
All models are available in a choice of AISI 304 or 316 stainless steel. Cast iron is offered the MI series only. Flow rates can range from less than1 l/h up to 130m³/h. Maximum discharge pressures can be up to 24 bar.
When properly sizing a pump, we need to know:
⇒ Product ⇒ Specific Gravity
⇒ Capacity (LPM) ⇒ Discharge Pressure (PSI) ⇒ Head Pressure (TDH)
⇒ Inlet Pressure (PSI) (Where NPSHₐ ≥ NPSHᵣ)
⇒ Viscosity (cP) - Ambient Temperature, Process Temperature ⇒ Solid Size & Content
Horizontal and vertical runs are important factors when determining head. Friction loss is critical to determining head pressure. To properly size a pump, the size and type of all fittings, valves and equipment must be taken into consideration.
