Rogers Engineered Progressive Cavity Pump System (RPS.PC)
Progressive cavity pumps are best utilized when the liquid being pumped has solids or lumps in it (think pumping jelly with whole fruits still inside that you don't want squished) or for pumping very viscous liquids that are shear sensitive (i.e. will split into their base components under stress).
A flexible, helical-shaped rotor rotates in a softer, typically rubber-based stator that can gently move the product through the pump. These are not just for low-pressure applications, these pumps can operate up to 1400 PSIG under the right conditions.
Multiple seal types and materials of construction are available to ensure that the pump will have the longest possible life given the specific application. The internals of the pumps do have some contact and wearing but given the appropriate selections - they can have a long, worry-free lifecycle.
Progressive cavity pumps can be paired with a piped inlet or an open inlet/hopper arrangement. They create powerful suction at the inlet that helps draw liquid or product into the pump and excel in uses where air or gas-liquid mixtures need to be primed into the pump prior to pumping the process liquid.
