Suction below, discharge above
HPX Center Port
The standard range. Suction enters at the bottom manifold and discharge leaves at the top — the arrangement most AODD installations are piped for.
Seven port sizes from 1/4" to 3", in polypropylene, PVDF, aluminium, cast iron and 304/316 stainless steel. Bolted fluid sections, an externally serviceable air valve, and no dynamic seals anywhere in the wetted path.

Maximum free-flow figures, measured with water at 20 °C. Actual duty depends on the installation — send us the duty point and we will size it.
How to specify one
Size and body, then the wetted path in flow-path order.
HPX 25 PP – PP / TF / TF
series · size · body — seat / ball / diaphragm. The example is a 1" pump with a polypropylene body, polypropylene seats and PTFE balls and diaphragms.
Send us the duty instead if that is easier — fluid, viscosity, solids, temperature, suction condition and the flow and head you need — and we will specify the pump.
Wetted material limits
The most restrictive wetted component governs the pump.
| Material | Minimum | Maximum |
|---|---|---|
| Polypropylene (PP) | +4 °C (+40 °F) | 65 °C (150 °F) |
| PVDF (KV) | +4 °C (+40 °F) | 93 °C (200 °F) |
| PTFE diaphragm (TF) | +4 °C (+40 °F) | 107 °C (225 °F) |
| Santoprene (ST) | −40 °C (−40 °F) | 107 °C (225 °F) |
| FKM / Viton® (VT) | −40 °C (−40 °F) | 177 °C (350 °F) |
| Buna-N (BN) | −40 °C (−40 °F) | 121 °C (250 °F) |
| Polyurethane (PU) | −40 °C (−40 °F) | 93 °C (200 °F) |
Temperature limits are based on mechanical stress only. Certain chemicals significantly reduce safe operating temperature — check chemical compatibility and temperature limits together, and size the pump so the whole duty cycle stays inside the wetted-material window. The most restrictive wetted component governs the pump.
