GMP High Head Self Priming Pumps

The GMP High Head Self Priming range is built for applications where water needs to be lifted to a significant height rather than simply moved along, with head capacities running from 25m up to 33m across the five models. Each pump uses an open impeller design that avoids suction loss, paired with a non-return valve on the inlet that keeps the pump primed between cycles, so re-priming after a stop-start is quicker and less hands-on.

Construction is cast iron with a stainless steel shaft and carbon mechanical seal, giving durability without the weight or cost of a fully stainless build. All models handle a maximum suction depth of 6 metres and liquid temperatures up to 70°C, and the two heaviest units in the range come pre-assembled on a skid plate to simplify installation and transport.

Facilities managers and contractors specify this range for clean or slightly contaminated water applications where standard flow rate isn’t the priority and vertical lift is. Typical uses include irrigation from a lower source, dewatering where water must be pushed up and out of an excavation, and general water transfer where the discharge point sits well above the suction point.

Choosing the right GMP High Head model

The two smallest models, EAEN and EB53, share identical performance (315 l/min at 25m head) and differ only in voltage: EAEN runs on 230v single phase, EB53 on 400v three phase. The mid-range EAEL and EADT models step up to 370 l/min at 33m head, again split by voltage rather than performance. The EAT8 sits at the top of the range with the highest flow of the five at 400 l/min, still at 33m head, and is 400v only.

Solids handling increases slightly as you move up the range too, from 5mm on the smallest models to 8mm on the EAT8. If your water source carries any debris, this is worth checking against your application before ordering. Since maximum suction depth and liquid temperature are identical across all five models, your choice really comes down to required head and flow, then voltage.
