What a chocolate pump has to do
Chocolate, cocoa mass and compound coatings are thick, fatty and sensitive to temperature. The pump must move them at a steady rate between melting tanks, storage tanks, tempering machines and depositors, and it must do so at low speed.
A positive displacement gear pump delivers the same volume at every revolution. The flow follows the speed of the drive, so you can meter chocolate by adjusting it.
FX series: stainless steel chocolate pump you can open for cleaning
The FX series is machined entirely from solid stainless steel, and chocolate is one of the products it was designed for. It strips down completely in a few minutes for internal cleaning, which matters when you change from dark to milk or to a filling. A heating or cooling jacket is available and the pump is prepared for C.I.P. washing. Six models cover theoretical flow rates from 19.4 to 247.1 l/min.
CR and NAV series for bulk chocolate transfer
For larger volumes we propose the CR series. Its heating jacket completely surrounds the pumping chamber, so the chocolate inside stays liquid during a stop and the pump restarts without strain.
Where the line and tanks are already kept warm, the flanged NAV series handles high flow rates without a jacket. Chocolate is among the fluids listed for both series.
Sizing a chocolate pump with our technical office
Tell us the product, the flow rate, the temperature you hold and the layout of the line. Our technical office in Bologna sets the model and the speed, usually with a geared motor unit for low revolutions.
The same approach applies to hazelnut cream and other high viscosity food creams. Write to us on WhatsApp or send the quote form.
