Honey pumps

Honey is dense, it crystallises and it does not forgive overheating or air. A honey pump has to move it slowly and keep it intact. Pompe Casali gear pumps, built in Bologna, Italy, transfer honey and dose it at a steady rate.

Honey pumps – Pompe Casali

What honey asks of a pump

Liquid honey becomes far thicker as the temperature drops, and with time it crystallises. Packers warm it gently to make it flow, because too much heat spoils aroma and colour. Air is the other enemy. A pump that whips air into honey leaves foam in the jar.

A positive displacement gear pump running at low speed moves a fixed volume per revolution and gives a steady, even flow.

FX series: stainless steel honey pump for packers

For honey packing and food manufacturing we normally propose the FX series, machined entirely from solid stainless steel. It dismantles completely in a few minutes, so crystallised residue can be removed, and it is prepared for C.I.P. washing. The heating jacket available on this series keeps the pump body warm so that honey does not thicken inside during a pause. The model is confirmed by our technical office.

ZV series: small honey pumps for dosing and filling

Honey is among the fluids listed for the ZV series, built for small flow rates from 0.47 to 102 l/min. It has threaded ports and flanges directly to the motor. Flow is proportional to speed, so the pump can meter honey into cereals, baked goods or sauces and feed a jar filler at the rate you set.

Choosing a honey pump

We need to know whether the honey is liquid or creamed, the temperature at which you work it, the flow rate and the length of the line. Our technical office in Bologna then indicates the model and the speed, usually with a geared motor for low revolutions. Send these details on WhatsApp or with the quote form.

Similar criteria apply to syrups and molasses. For other ingredients see pumps for the food industry.

Frequently asked questions

Can a gear pump move crystallised honey?

Honey should be brought back to a pumpable state first. Tell us its condition and temperature, and our technical office will advise on the speed and on a heating jacket.

Does pumping damage the honey?

A gear pump at low speed limits stress on the honey and the risk of drawing in air. The speed is set by our technical office for your flow rate.

Can the pump feed a jar filling machine?

Yes. Flow is proportional to speed, so the pump supplies the filler at a constant rate that you set from the drive.
