Henan Dayu Industry Co., Ltd. is a professional structural machinery manufacturer in China, with CE, ISO. Our company is dedicated in shotcrete machines and other construction machinery. Dayu business scope includes: 1. Shotcrete machine 2. Plaster Machine 3. Mortar Pump 4. Grout Pump 5. Industry Hose Pump 6. Grout Mixer Dayu shotcrete machine kinds: 1. Dry-mix: The dry mixture of cement and aggregates is filled into the machine and conveyed with compressed air through the hoses. The water needed for the hydration is added at the nozzle. 2. Wet-mix: The mixes are prepared with all necessary water for hydration. The mixes are pumped through the hoses. At the nozzle compressed air is added for spraying. DY-RPB7 Wet mix shotcrete pump: DY-RPB7 shotcrete pump incorporates the advantages of wet-mix spraying with the low cost of a dry-mix machine. It is a machine that fills the void in the medium to small capacity class, but keeps the same characteristics of larger pumps. DY-RPB7 is the machine you have been waiting for! It incorporates the advantages of wet-mix spraying with the low cost of a dry-mix machine. It is a machine that fills the void in the medium to small capacity class, but keeps the same characteristics of larger pumps. The Risen RPB7 is an oil hydraulically driven twin-piston pump especially suitable for hand-spraying, concrete pumping, grouting, artificial soil seeding, mortar spraying, refractory material spraying and with small manipulators. It is extremely simple in construction and operation. It is very compact, durable and versatile enough for any site in the world. DY-RPB7 Wet-mix shotcrete pump features: 1. Thick flow conveying method with hand-spraying make the concrete spraying is even, steady with less air consumption comparing to thin flow conveying method. 2. Dayu-RPB-7 is a high efficiency machine with a longer conveying distance, horizontal 120m and vertical 50m. 3. Simple CE standard electrical system controls provide fool-proof operation 4. Soft-start protects electric system and motor. 5. Two independent oil pressure circuits. 6. Main oil is supplied by a high-pressure, variable-flow, axial piston pump. A gear pump provides separate circuit for the dosing pump. 7. Setting of the desired dosing values by hand-wheel 8. Double piston pump with S-tube and change-over cylinders for a positive action. 9. Self-sealing, superhard sealing ring and plate. 10. Automatically reversing pistons relieve the conveying system when blocked. 11. Tough hopper with vibrator and grill designed for work with steel fibres. 12. Centrally positioned lubrication point for easy service. 13. Low weight is an advantage for transport.
