Pump Tec

Pumptec pumps are the quiet standard in portable extractors — they run at moderate pressure, they run for years, and when they do stop it is almost always a seal, a valve or a regulator rather than the pump body.

That is the argument for holding kits rather than spare pumps. A rebuild is an afternoon on the bench; a replacement pump is a lead time.

The range covers the 205V and 207V valves and O-rings B kit and the 205/207V plunger and seals kit; the plunger and Buna seal kit 10001 for 114T and 112T pumps; the 205v/207v C cam bearing for 230 V; the 500 psi brass pressure regulator with silver spring and its repair kit for the PT021 and PP15-808133; a 600 psi gauge for Olympus and Razorback; Kit "B" covering Force 250, 112, 113, 217, 350 and 356; the Force 250 (112T) 200 psi pump; and a Marathon 1/2 hp 120/230 V pump motor.

How to choose

Symptom points to the kit. Weeping at the head is seals. Pressure that pulses or will not hold is valves. Pressure that has drifted down over months is usually the regulator, not the pump.

The cam bearing is the one people miss. A pump that has become noisy under load, rather than losing pressure, is often the C cam bearing. Replacing seals will not quieten it.

Check the voltage on electrical parts. The C cam bearing listed here is the 230 V item and the Marathon motor is dual voltage at 120/230 V. Confirm what the machine runs before ordering.

Fit a gauge if the machine does not have one. You cannot diagnose a regulator, or prove a rebuild worked, without reading pressure. A 600 psi gauge is the cheapest diagnostic in the range.
