Tri-Clover® Pump Seals

We design and manufacture mechanical seals for the Food, Dairy, and Pharmaceutical Industries. Our proven innovative seal design will allow the mechanical seal to perform while remaining free and clean of product buildup; this will result in a reduction or elimination of product contamination.

T-218 seal replacementOur design philosophy is to “Keep it Simple”. This means low costs, better reliability, ease of installation, and improved seal hygiene. Our Zero Maintenance Seals will outperform your existing O.E.M. mechanical seals, guaranteed.

We manufacture and stock many mechanical seals, both ZMT engineered and replicated O.E.M., for many sanitary centrifugal and positive displacement pumps. Contact the factory regarding the equipment in your plant for information about how ZMT engineered seals can be used in your application.

All ZM Technologies’ engineered mechanical seals are waterless (flushless), and are repairable for a fraction of the price of new.

Our mechanical seals are easier to install than the OEM, and offer 3-4 times the life of the original seal.

We sell O.E.M. replicated seals for the C, SP, CL, and EH model pumps. Our inventory includes E, D, and DG style seals in a range of materials.

All components are available as individual parts or as O.E.M. style kits.
