Polypropylene (PP) Centrifugal Process Pumps

A PP centrifugal process pump is an injection-molded polypropylene pump built for hazardous, corrosive and acidic fluid transfer. All wetted parts casing, impeller and backplate are solid polypropylene, eliminating metal contact with the process fluid.

Shiv Pumps PP centrifugal pumps are rated for fluid temperatures up to 90°C and offer 100% resistance to corrosive acids, alkalis and aggressive chemical effluents, thanks to solid injection-molded polypropylene construction.

These pumps use an externally mounted Teflon bellows mechanical seal with high-purity ceramic/carbon faces, isolating metallic spring elements from the media to prevent seal degradation and eliminate leakage.

The high-tensile steel shaft is shielded by a high-alumina ceramic sleeve, which minimises friction, reduces heat generation and extends service life of the sealing interface in continuous-duty chemical applications.

PP centrifugal pumps are widely used in chemical manufacturing, electroplating, acid pickling, wastewater/ETP treatment, fertiliser production and pharmaceutical process lines handling corrosive or hazardous fluids.

Yes. The dynamically balanced semi-open impeller handles clear liquids, crystalline solutions and chemical slurries containing minor suspended solids without clogging or a drop in discharge pressure.

PP pumps are a cost-effective choice for most acids, alkalis and general corrosive duties up to 90°C, while PVDF suits stronger chemicals, solvents and higher temperatures, and stainless steel suits non-corrosive, high-pressure or abrasive-free applications.

Yes. Shiv Pumps engineers custom PP centrifugal pump configurations flow, head, seal design and connections to match specific process requirements, working directly with customers to finalise specifications.
