There are some pumps that are always in demand and this Southern Cross 2.5" x 5" high-head pump is up there with the best of them!!


Suction and discharge on this pump are both 1.25". Our documentation states that this pump has a head of 500 feet and, at 50 strokes per minute (260 rpm at the pump) it will deliver 500 gallons per hour (or approx 2,250 litres) and will only need a 4 hp electric motor to drive it to the maximum head - we've been told that the equivalent in petrol or diesel would be approximately double!!

This pump has the added benefit of having a large, extra air chamber on the discharge side of the pump to help overcome any friction that may happen when pumping to such a high head - an absolute bonus!!!


The configuration of the wet-end makes these pumps very heavy! Attached is a PDF document showing more detail of the configuration of the valve set up - the assembly is complete in the first photos and the components and gradual fitout is progressively shown from last to first photos. See attachment here!


The electric motor attached is 3 hp and is a genuine Southern Cross build - they last forever and this one has been completely checked out and is fully operational.


This pump is on consignment and is pretty much in as-received condition. We have had the cylinder liner honed, the valves refaced and fitted new valve rubbers, springs and gaskets.
