Small flow rates, high performance

ZV series gear pumps for small flow rates

The ZV series is the small gear pump of our range. It was born from our experience in metering fuels and lubricants on Formula 1 engine test benches. Today it doses and transfers a long list of industrial and food fluids.

Theoretical flow rates in l/min.

A compact pump for metering

The ZV has threaded ports and flanges directly to the motor. Pump and motor form a short unit that fits inside a machine or on a small skid. The flow is proportional to speed, so you regulate the dose by regulating the motor.

Fluids handled by the ZV series

The list is wide: thermal oil, edible oils, soap, shampoo, wine, molasses, honey, detergents, diesel, kerosene, fuel oils, greases, caustic soda, acids and bases, resins, solvents, glues, paints, ink, hot-melt, isocyanate and polyol.

Common duties are dosing resins and two-component products, feeding burners with fuel oil and diesel, metering paints and pigments and adding molasses to animal feed.

Ten models and materials

Ten sizes cover displacements from 1.05 to 70.7 cm³/rev. Bodies are available in cast iron or AISI 316 stainless steel, with or without heating chamber. The choice depends on the fluid, and our technical office in Bologna, Italy, makes it with you.

How we supply it

You can order the bare shaft pump, foot mounted (B3) or flange mounted (B14), the pump flanged to its electric motor, or a geared motor unit for thick fluids that need low speed. For larger flow rates the next step is the NAV series.

Frequently asked questions

What is the smallest flow rate of the ZV series?

The catalogue range starts at 0.47 l/min. For your duty the technical office checks the model and the speed.

Is the ZV series available in stainless steel?

Yes. The body is available in cast iron or in AISI 316 stainless steel.

Can I use the ZV series for flammable liquids?

Fuels and solvents are among its fluids. ATEX documentation is available on request.
