Purpose-Built Pumps for Moving Diesel

Moving fuel isn’t the same job as moving water, and Pentair’s diesel transfer range is designed around that difference. These are self-priming liquid ring pumps developed specifically for diesel, sold under the Nocchi name. Two families make up the range: the PGA for fixed installations and the Delta for portable use.

Liquid Ring Design with Cast Iron Durability

Pump casings and motor brackets are cast iron to EN GJL 200, with a brass finned impeller and AISI 416 stainless steel shaft. Sealing uses a graphite mechanical seal on a ceramic counterface with an NBR O-ring, plus a safety tube to discharge any leakage. Flows run from around 40 to 60 litres per minute at up to 6 bar, with liquids to 50°C and a 5 metre suction lift using a foot valve.

Portable or Fixed, Which Suits You?

If the pump lives in one place, plumbed into a tank and dispensing point, the PGA is the natural pick in ¾ inch or 1 inch. If it needs to travel between tanks, vehicles or sites, the Delta gives the same hydraulics with a carrying handle, on/off switch and fitted cable. Both are diesel only, never petrol, chemicals, water or low flash point liquids.

Transferring diesel in agricultural, commercial and light industrial settings. Common uses include delivery and dispensing assemblies, refuelling farm machinery, and small pumping stations.

No, and this one matters for safety. Both ranges are approved for diesel only and must not be used for petrol, chemicals, water or any low flash point liquid, as doing so creates a serious fire and explosion risk. Contact us if you need to move a different fluid.

The hydraulics are shared, so performance is comparable at equivalent sizes. The Delta adds a carrying handle, on/off switch and fitted power cable for portable use, while the PGA is configured for fixed installation.

From around 40 to 60 litres per minute across the range. The PGA 40-30 and Delta sit at the lower end with ¾ inch connections, while the PGA 60-40 offers higher flow through a 1 inch connection.
