Diesel Engine Stationary Trailer concrete pump (TM90D-20)

1. Powerful machine adopts CATERPILLAR diesel engine.

2. Import generator is optional.

3. The high quality hydraulic valves and oil pump use Germen REXROTH products.

4. The valve for change-over from high pressure to lower pressure is designed to be easily controlled, which can adjust the condition of the pump easily in accordance with the requirement of job site. Dismantle the tube is not necessary so that it can avoid the pollution.

5. Advanced hydraulic system which change direction hydraulically can run without electrical part.

6. Concrete piston can run back to washing tank, which can easily change the piston and be convenient for maintenance.

7. Tungsten steel glasses shaped plate and cutting ring guarantee long using life.

8. Hydraulic outriggers make easily positioning.

9. Pump can be easily washed.
