Hydra-Cell H25SKPEHFTHC Polypropylene Seal-Less Diaphragm Pump
The Hydra-Cell H25SKPEHFTHC is a rugged, seal-less diaphragm pump built with a polypropylene head and EPDM diaphragm, designed to move demanding fluids without the leaks and downtime common to traditional seal-based pumps. Its hydraulically balanced diaphragm design allows the pump to run dry without damage, tolerate abrasives and particulates, and keep operating reliably even when conditions aren't ideal — making it a dependable choice anywhere consistent, low-maintenance fluid transfer matters.
Because it has no packing, seals, or cups to wear out, this pump is well suited to a wide range of settings beyond any single industry — from car wash systems and food processing to water treatment, agricultural spraying, and general industrial chemical transfer. The polypropylene construction offers strong chemical resistance for aggressive fluids, while the multi-diaphragm design helps deliver smoother, low-pulsation flow that reduces strain on downstream components. For operators who need a pump that keeps running through tough conditions with less upkeep, the H25SKPEHFTHC offers a practical, long-term solution.

Frequently Asked Questions
Q: Can the H25SKPEHFTHC be used with corrosive or aggressive chemicals?
The polypropylene head and EPDM diaphragm give this pump strong resistance to a wide range of corrosive fluids, making it a good fit for chemical transfer applications.
Q: What happens if the pump runs dry accidentally?
Thanks to its seal-less diaphragm design, the H25SKPEHFTHC can run dry without sustaining internal damage, reducing the risk of costly downtime.
Q: How often does this pump require maintenance?
Because it has no packing, seals, or cups, maintenance needs are significantly lower than traditional pumps, with most upkeep limited to periodic oil and diaphragm checks.
Q: Is this pump suitable for continuous industrial use?
Yes, the tapered roller bearings and rugged construction support continuous-duty operation across many industrial settings.
Q: Does this pump work well with fluids containing particulates?
Yes, the pump's design allows it to handle abrasives and particulates that would damage many conventional pump types.
