GMP Fuel Oil High Volume 'Red' Diesel Transfer Pumps

The GMP Fuel Oil High Volume RED Diesel Transfer Pumps are a range of self-priming electric pumps built specifically for transferring diesel, gas oil, and paraffin. These pumps are not suitable for petrol. The RED designation identifies this as GMP’s fuel-rated series: the cast iron body is fitted with a Viton mechanical seal and Viton check valve, both essential for compatibility with petroleum distillates. Standard water pump seals would swell and fail quickly in fuel service. The open impeller design provides good self-priming performance, with suction depth to 6 metres and maximum liquid temperature of 70°C.

The range is unusually broad in voltage coverage: models are available in 110V (site supply), 230V (single-phase), and 400V (three-phase), across port sizes from 1-inch to 3-inch. This makes the RED range suitable for everything from small on-site fuel transfer with a CTE socket to large-scale industrial diesel decanting. An ATEX-rated variant is also available separately for use in hazardous zone environments.

Choosing the Right Model

Port size is the primary selection factor. 1-inch models (EA2L/EA2M) deliver up to 140 l/min and are suited to filling small plant, generators, or fuel storage jerry cans. 1½-inch models (3516/3501) step up to 290 l/min, appropriate for road plant refuelling or medium tank filling. 2-inch models (EA2V/EA1S) reach 450 l/min and are the most common choice for bulk diesel transfer on construction sites and farms. The 110V EAHA 2-inch model is designed specifically for UK site power where CTE (commando) supplies are standard. 3-inch models (EA9C/EAM7/EANS) handle 850 l/min up to 1,200 l/min and suit high-volume commercial or industrial fuel transfer applications.
