Versatile, self-priming pumps for viscous inks, varnishes, coatings, adhesives and laminates — safe for hazardous areas.
Powerwise stocks polypropylene double diaphragm pumps from 1/4″ up to 1″ inlet/outlet, all convertible to assisted gravity return. Larger sizes up to 3″ are available in polypropylene, stainless steel, Hastelloy and cast iron construction for demanding applications.
Double diaphragm pumps are the go-to choice for higher-viscosity inks and coatings that exceed what a centrifugal pump can efficiently handle. If you’ve experienced surging with a diaphragm pump — especially with enclosed doctor blade chambers — a Filter/Surge Suppressor eliminates the issue.
Accessories include carts, stainless steel tanks and lids, and siphon tubes for large containers and drums. Powerwise also stocks a full range of spares for our own pumps and other major brands, including ARO, All-Flo, Graco, Wilden, Vers-a-matic and Yamada.
ATEX-approved double diaphragm pumps are available for flammable-ink environments that require explosion safety compliance.
Pump selection depends on your press, your ink’s viscosity, and your operating environment. Tell us about your project and we’ll recommend the right fit.
