Aliva-272 shotcrete pump

The Aliva-272 is a compact and powerful twin-piston pump with an S-tube, developed for shotcrete but also usable for plain concrete pumping. The pump operates almost pulsation-free and is supplied with an integrated, synchronised Aliva-403.6 dosing unit for accelerator. The control system adjusts the accelerator dosing in proportion to the concrete output, and the output can be infinitely adjusted from the control cabinet or by remote control. The concrete output and dosing are shown on a display. The Aliva-272 is particularly suitable for steel-fibre shotcrete, and is supplied as standard with a steel-fibre grate and a rubber collar in the hopper.

The theoretical output is 3–20 m³/h with a stroke volume of 12.4 litres. The maximum aggregate size is 16 mm when spraying and 32 mm when pumping, and with a concrete pressure of up to 80 bar the concrete can be conveyed up to 300 metres. The manufacturer recommends steel pipes for conveying distances over 80 m. The pump is available with electric drive or a diesel engine:

• Electric drive: 3 x 400–480 V, 37 kW
• Diesel engine: Deutz 3-cylinder, 34.5 kW / 47 hp, EU Stufe IIIA / US EPA Tier 3

The pump can be supplied on a forklift-compatible frame (skid), on a road-approved trailer or on a two-axle trailer with a 1000 litre accelerator tank.

The machine is designed for easy operation, servicing and cleaning. The cover can be opened fully, the hopper is hinged, and the components are positioned with accessibility in mind. The pump can also be run in reverse to relieve the pressure in the delivery line and for cleaning. The standard equipment includes an agitator, electric vibrator, air manifold with solenoid valve and lifting points on top of the pump. Additional equipment includes a hydraulic high-pressure washer, reducer kit DN125–DN65/180°, cable or radio remote control, a particulate filter for the diesel version and original accessories such as spray nozzles, pump hoses and couplings from the Aliva Converto range.
