Wanner Hydra-Cell D25K52-JHFHH Complete Fluid End Pump Repair Kit

This is a new, genuine Wanner Engineering Hydra-Cell Complete Fluid End Repair and Rebuild Kit, part number D25K52-JHFHH, designed for the Hydra-Cell D25 series positive-displacement, seal-less diaphragm pumps manufactured by Wanner Engineering, Inc. (Minneapolis, MN). The D25K52 base kit designation covers the full fluid-end rebuild for a D25-series pump head, and the suffix -JHFHH encodes the specific materials for wetted components: J = PTFE (polytetrafluoroethylene) diaphragms, H = Hastelloy C check valve balls, F = 316 stainless steel check valve seats, H = Hastelloy C check valve springs, H = Hastelloy C hardware. Kit contents visible in the photos include multiple PTFE diaphragms, stainless steel check valve bodies and seats, check valve springs and retainers, PTFE and elastomeric O-rings, a body O-ring/cord stock seal loop, and a packet of Loctite thread adhesive — constituting a complete service replacement for all fluid-end wear components. The Hydra-Cell D25 is a multi-diaphragm, hydraulically-actuated pump rated for high-pressure, leak-free service in chemical dosing, high-purity fluid transfer, and abrasive slurry applications where seal-less operation is required; this material combination (PTFE/Hastelloy/316 SS) is suited for aggressive chemical service including acids, caustics, and solvents.
