1. Henan Coal Science Research Institute Keming Mechanical and Electrical Equipment Co. , Ltd. (the former Keming Mechanical and Electrical Department of Henan Coal Scientific Research Institute) is a holding subsidiary of Henan Coal Scientific Research Institute Co., Ltd. Our company is dedicated to the research and development, production and sales of shotcrete machine, grouting pump, and complementary products. Up to now, we have developed more than 50 kinds of products, covering spraying machines, pumps and other series of products.
2. Industrial Hose Pump is the very mature products with different kinds of standard models and many special models designed as the customer’s request. The working pressure ranges from 0.6~1.5 MPa, and output capacity from 0.01~50 m3/h.
1. Free exchange of suction inlet and discharge outlet. When the pump is blocked, reversing pump can discharge the obstruction.
2. No valve operation, no back flow, stable pumping flow, low fault rate.
3. Convenient maintenance, less wearable parts (except extruded hose).
4. High vacuum, strong self-suction capacity.
