Polypropylene Vertical Centrifugal Process Pumps

The vertical, bearing free design keeps wetted parts limited to polypropylene and PTFE sealing rings with no shaft seal exposed to the process liquid, which removes a common leak point entirely.

It is built for highly corrosive fluids such as hydrochloric acid, sulphuric acid between 30 and 80 percent concentration, and nitric acid, where even trace metallic contamination is unacceptable.

Rinku Engineers manufactures this pump at its facility in G.I.D.C. Vatva, Ahmedabad, Gujarat, and supplies it in both conventional and tailor made configurations.

Filtration, transferring corrosive chemicals, slurry handling, and sewage or wastewater treatment plants are the primary applications for this sealless vertical design.

Bearings are lubricated by the pumped product itself or by fresh water, since the bearing free design relies on radial vanes on the impeller to maintain flow through the sleeve bearing area.

Price depends on immersion depth, mounting plate configuration and capacity, so Rinku Engineers provides an estimated quotation once the tank size and duty are known.

Yes, as the manufacturer, Rinku Engineers supplies the polypropylene vertical centrifugal process pump directly from Ahmedabad, in conventional or tailor made configurations to suit tank dimensions.

Yes, it is part of the AYUSH and polypropylene process pump range Rinku Engineers exports to the Middle East, Africa and Southeast Asia.

The standard PP pump is a horizontal design with a bearing frame and mechanical seal or gland packing, while this vertical version is bearing free and sealless, aimed at zero contamination and space constrained installations.

Yes, the pump is available with polypropylene mounting plates in addition to conventional metal mountings, keeping all wetted and near-wetted surfaces non-metallic where required.

Yes, sewage and wastewater treatment plant service is a listed application, alongside filtration and general corrosive chemical transfer duties.

PTFE sealing rings are used rather than a dynamic mechanical seal, which suits highly corrosive and hazardous liquids where a conventional seal face could wear quickly.

Yes, Rinku Engineers offers tailor made configurations in addition to its conventional range, so column length and mounting can be adapted to a customer’s tank or sump.

In pharmaceutical, high purity chemical or specialty processing, even trace metal ions from a pump can contaminate the product, so an all polypropylene wetted path avoids that risk entirely.

Yes, slurries are listed among its applications alongside strong acids, since the bearing free design tolerates some abrasive content without a packed seal to wear out.

Rinku Engineers provides technical guidance on immersion depth and tank fitment along with spare wear rings and impellers directly from its Ahmedabad facility.

Yes, alongside conventional sealed pumps, Rinku Engineers has manufactured sealless, bearing free polypropylene vertical pumps as part of its centrifugal process pump range for corrosive chemical handling.

Yes, mounting vertically directly into a tank or sump removes the need for a separate base, baseplate and coupling guard that a horizontal pump would require.
