External gear pumps, Bologna, Italy
Pumps for bitumen, molasses and the fluids other pumps cannot move
Since 1955 we have designed and built self-priming gear pumps with cast iron or AISI 316 stainless steel bodies and heating jackets, for fluids that are thick, hot, abrasive or solid at room temperature. Tell us the fluid: we will tell you the pump.
- Flow rates
- 0.47 to 2,800 l/min
- Fluids
- bitumen, molasses, resins, oils, food
- Heating
- jacket, cartridges, hot-point
- Materials
- cast iron · AISI 316 · SEF versions
Pick the fluid, find the pump
Each page explains why that fluid is hard to pump, which series to use and which data we need to size it.
Bitumen, asphalt and oils
Molasses and viscous fluids
Resins, adhesives and chemicals
Food, cosmetics, stainless steel
Five series, one principle
All our pumps are positive-displacement external gear pumps: constant flow proportional to speed, self-priming, built-in overpressure valve. Body, heating and size change. How an external gear pump works.
- Serie CR Heated-jacket gear pumps Flow at 950 rpm30 – 2,812 l/min
- Serie SB For bitumen sprayers Flow at 950 rpm57 – 1,093 l/min
- Serie NAV High-viscosity fluids Flow at 950 rpm54 – 2,770 l/min
- Serie ZV Small flows and dosing Flow at 950 rpm0.47 – 102 l/min
- Serie FX AISI 316, food-grade Flow at 950 rpm9.2 – 247 l/min
How we get to the right pump
Describe the fluid
Type, working temperature, flow in l/min or m³/h, back-pressure, and whether it is abrasive or solidifies when cold. Two lines on WhatsApp or the quote form are enough.
Receive the technical proposal
From our Bologna factory we indicate series, model, drive, heating system and materials, with real flow rates at the planned speed.
A pump built for your plant
Design and machining in-house, ISO 9001:2015, ATEX documentation when needed. Direct support from the people who designed the pump.
Describe the fluid, we will size the pump
Fluid type, temperature, flow rate and pressure: with these data our Bologna factory replies with the recommended model, drive and heating system.
