More about this product
Product overview
The Pedrollo NGA 2B – PRO is a 0.55 kW (0.75 HP) open-impeller centrifugal pump on a 400 V three-phase supply, built entirely in AISI 316 stainless steel. It covers 50 to 450 l/min with a working head of 9.4 m down to 4 m, the same duty as the matching cast iron NGA.
AISI 316 resists chlorides, so the NGA-PRO suits sea water intakes, brackish and saline water, water treatment, fish farming and food and drink premises where hygiene and corrosion resistance matter. The open impeller lets it pass water with light suspended solids and fibres without clogging. Install indoors or under cover.

Frequently asked questions
What is the difference from the NGA?
The hydraulics and performance are identical. The NGA has a cast iron pump body with a stainless impeller; the NGA-PRO is stainless steel throughout, including the body, backplate and shaft.
Can it pump sea water?
Yes. AISI 316 stainless steel resists chlorides, so it suits sea and brackish water. Rinse through with fresh water after use if it will stand idle.
Is it self-priming?
No. It needs a flooded suction or a foot valve on the suction line.
What solids can it pass?
Water with a small amount of suspended solids and fibres. It is not a sewage pump.
