Professional impeller honey pump 1.5 kW 400V DN50

01 · HOW IT WORKS

Flexible vanes: it primes itself and gives no pulsing

The rotor carries elastomer vanes that bend as they pass the narrowing in the housing and spring back on the way out: that flexing creates the vacuum that draws without hand priming and pushes a continuous flow, without the knocking of a piston pump. It is self-priming, so it can draw from a drum above the liquid level, and it takes soft solids in suspension. In exchange, flow changes with viscosity: the 1,920 kg/h are with fluid honey and no head, not a promise with honey at 18 °C.

02 · THE 50 BORE

The difference between pumping and forcing

The fittings are DN 50, not DN 40 or an inch and a quarter: with thick honey or honey starting to set, a narrow bore loads the motor, heats the product and breaks vanes. With 50 mm of bore the honey comes in easily and the real flow stays near the nominal at 20-25 °C. That same bore is what lets it move the mix of wax and honey leaving the uncapping tray towards a cappings spinner: one machine for two stations in the room.

03 · THE MOTOR

Three-phase with a gearbox, and it reverses

The 1.5 kW geared motor at 400 V brings the speed down to a gentle regime, which is what avoids emulsifying the honey and drawing in air, the classic fault of pumping fast. Rotation is reversible: you empty a length of hose or purge the circuit without dismantling anything. Being three-phase it needs an industrial supply and connection by an electrician; if the room only has single-phase 230 V, the catalogue alternative is the 900 L/h pair (2949, 2950).

04 · WHERE IT FITS

A room with big tanks, not a weekend honey house

It is the pump of the room that moves several hundred kilos a day between 500 to 1,000 kg tanks, the uncapping tray and the filler. The sizing rule is to work at around 30-60 % of capacity: a generous pump turning slowly lasts longer and treats the product better than a tight one at full tilt. To empty 300 kg drums or IBCs from the top, without touching the tap, there is the submersible (3257); for single-phase transfer on a trolley, the 900 L/h pair.

05 · BEFORE YOU BUY

The pump is supplied; hoses, fittings and the electrical connection come separately.

⚠ PRECAUTIONS

Never dry: with no honey the vanes rub the housing and burn out. Filter before pumping, because a metal sliver wrecks the rotor. Product below 40 °C in continuous use. Clean at the end: honey setting inside blocks the rotor. Three-phase connection by an installer.
