Groz Rotary Hand Pump 25mm – Barrel Oil Transfer (GNB-25/3R)

The Groz GNB-25/3R is a heavy-duty rotary hand pump designed for transferring diesel and petroleum-based fluids from 50–205 litre barrels. Built from cast iron with hi-nitrile rubber seals, it features a telescopic feed shaft and delivers approximately 5 litres per 20 turns, with the ability to pump in either direction via reverse handle turns. Supplied complete with suction tube, bung nut, and steel discharge spout (3/4" NPT thread), it's ideal for workshops, fleet maintenance, and industrial facilities requiring reliable manual fluid transfer without electric power.
