Progressive cavity pumps are a self-priming positive displacement pump used for conveying or dosing of liquids such as water, viscous or abrasive media and liquids containing solids (soft or hard).
The ProMinent Spectra pumps are available as block or bare shaft design and feature our special cardan joints. Capacities are from 1l/h to 450 m3/h.
Spectra Cardan joints are fully encapsulated by a robust rubber boot. Each end is retainedby stainless steel reusable bands and sits in machined slots for maximum grip.The cardan joint is a proven heavy-duty universal type joint. This allows a simple construction without the inherent disadvantages of pin and other types of joint. Each arm of the joint pivots independently, thus giving a flexible robust joint that is small, simple and effective.
