Edible oil pumps

Edible oils are easy to pump when they are warm and clean. They are less easy when they are cold, when they solidify or when they must be metered accurately into a recipe. Pompe Casali builds self-priming gear pumps for vegetable oils and fats in Bologna, Italy, in sizes from dosing to bulk transfer.

Edible oil pumps – Pompe Casali

Why a gear pump suits edible oils

Oil lubricates the gears as it passes, which is the ideal working condition for a gear pump. The pump is positive displacement, so each revolution delivers the same volume and the flow rate does not drift when the oil thickens in a cold store.

It is also self-priming and can draw from drums, containers and tanks set below the pump. Our technical office checks the suction layout with you.

ZV series: dosing pumps for edible oils

Edible oils are among the fluids listed for the ZV series. It is a compact pump with threaded ports that flanges directly to the motor, built for small flow rates from 0.47 to 102 l/min. Use it to meter oil into doughs, sauces and preserves or to feed a filling machine. Flow follows speed, so you adjust the dose from the drive.

FX and NAV series: stainless steel and bulk oil transfer

Where the pump must be opened and washed, we normally propose the FX series, machined entirely from solid stainless steel, quick to dismantle and prepared for C.I.P. washing.

For tanker unloading and transfer between storage tanks we normally propose the flanged NAV series, with theoretical flow rates up to 2770 l/min. The model is confirmed by our technical office for your oil and your duty.

Fats that solidify: palm oil, coconut oil, cocoa butter

Some fats are solid at room temperature and must be kept warm from tank to point of use. A pump with a heating jacket holds them liquid during a stop. The jacket is available on the FX series, and the approach is the one we use for chocolate.

Tell our technical office in Bologna which oil or fat you handle, at what temperature and at what flow rate. Write on WhatsApp or use the quote form. For other ingredients see pumps for the food industry.

Frequently asked questions

Can a gear pump meter edible oil accurately?

A gear pump delivers a fixed volume per revolution, so flow is proportional to speed. You regulate the dose by regulating the drive. For small quantities we use the ZV series.

Stainless steel or cast iron for edible oil?

Our pumps are built with a body in cast iron or in AISI 316 stainless steel. The choice depends on your product and your hygiene requirements, and our technical office advises you.

Can the pump draw oil from a drum or an underground tank?

Yes, the pumps are self-priming. The suction lift depends on the oil and on the pipework, so send us the layout and we will check it.
