1.The product use　
Mining Concrete Pump is explosion isolation and full hydraulic-type, driven by motor, with coal security signMEF130319, it is suitable for high voltage in the coal mine well and long distance conveying explosion-proof pump, suitable for pumping concrete, mortar, paste material, etc. Can be broadly used as the coal mine filling, grouting, guniting, gob-side entry retaining, backfill, Water storage, laying floor, mine drainage, close rapidly and so on.
2.Product Characteristics
◆ The concrete pump is adopted pilot-controlled automatic control system except the explosion-proof motor, no other electrical control components.
◆ High pumping pressure solving the long-distance pumping requirements.
◆ large discharge capacity, the output can be adjusted from 0 to 30 at the same time.
◆ Low aggregate requirement, the max. aggregate diameter is 40mm and so it can be used broadly.
◆ With reversing pump function: it can be a way to clear away the pipe if the pipe is blocked shortly.
3.Technical characteristics
◆ Hydraulic system: the main oil pump and hydraulic valve are international famous brand, stable and reliable, full hydraulic reversing open hydraulic system, high reliability, reversing impact is small, low oil temperature, the hydraulic system can clean by itself. Large output: little output if the pressure is high, high output if the pressure is low, you can choose according to the conveying distance and delivery requirements in engineering.
◆ Power system: choosing the domestic well-known brand of coal mine explosionproof motor, durable, safe and easy  maintenance. Explosionproof is ExdⅠ.
◆ High-efficient pumping system: hopper is new designed and welded with high-strength steel, high intensity, double arc structure, no dead angle, no concrete store up, the flowability and imbedibility of concrete, mortar and paste are greatly improved.
◆ Wear-resistant technology: Wearing parts adopt high-tech material and advanced technology improving the funtion of the product.
◆ Lubrication technology: adopting self-lubrication technology of hydraulic synchronization, automatic centralized oil supply system, sufficient oil supply and better lubrication.
