TWX pumps are non-self-priming, single-stage, cantilever centrifugal volute pumps with axial inlet port, radial outlet port, and horizontal shaft on the base frame. They are available in PN16 and PN25 body pressure versions. The pumps consist of a hydraulic part, an elastic pin coupling or a spacer coupling, a coupling guard, and air-cooled asynchronous motors mounted on a common base frame. The pumps are fitted with a mechanical shaft seal. The pumps are of the back-pull-out design, that is you can remove the motor, motor stool, and impeller without disturbing the pump housing or pipes.
