Cement injection groups - Technical data

Designed for particularly high wear resistance BUNKER pumps guarantee hundreds of m³ injected mortar.
That's thanks to tried-and-tested cast iron pumping unit, with pistons and valves chrome-plated to the right thickness. The alternate movement is provided by a motor coupled to a maintenance-free gearbox. Tightness is ensured by a special gasket in abrasion resistant polyurethane. So we have high reliability and wear resistance, but not only that _ BUNKER is also easy to dismantle, enabling quicker cleaning and maintenance whenever necessary.

The electric panel, protected against impact and water sprays, conforms to European directives. Made with highly reliable components, it supports the many ON/OFF activations typical of pressure control pumps. It is equipped with a thermal cut-out for the electric motors, a handy phase inverter and an emergency push-button. The hour counter (standard supply) helps you plan both work and maintenance.

All pumps with the electronic pumping facility are supplied with a button-board with 20 metre cable. This means the operator can activate it directly from the injection point.
A great advantage!

The pumping unit (easy to dismantle and clean) with pistons chrome-plated to the right thickness, assures hundreds of m3 of injected volume. All done worry-free and with no clogging.

The pressure-switch (standard supply) enables you to adjust pressure to the value you require, automatically stopping the pump when that value is reached.
The pressure gauge (in glycerine bath) makes for easy to read pressure values.

A handy valve allows the mixture to be discharged into the lower agitator before the pumping cycle begins. It operates by squashing a rubber tube, which ensures long life and no maintenance because no metal parts come into contact with cement.

The upper mixer is supplied with a safety grid allowing easy passage of material but not access by the operator's hands.
The agitating blades themselves, as well as their shape and number, are designed to guarantee perfect mixing.

A boll cock, directly connected to the mixer, facilitates loading water needed for the mixture. On request, the whole injection pump range can be equipped with an air motor to allow use on sites without electrical energy or with an explosion risk.
