Risen 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.

Features:

• Thick flow conveying method with hand-spraying make the concrete spraying is even, steady with less air consumption comparing to thin flow conveying method.
• RISEN RPB7 is a high efficiency machine with a longer conveying distance, horizontal 200m and vertical 70m.
• Simple CE standard electrical system controls provide fool-proof operation
• Soft-start protects electric system and motor.
• Two independent oil pressure circuits.
• Main oil is supplied by a high-pressure, variable-flow, axial piston pump. A gear pump provides separate circuit for the dosing pump.
• Setting of the desired dosing values by hand-wheel
• Double piston pump with S-tube and change-over cylinders for a positive action.
• Self-sealing, superhard sealing ring and plate.
• Automatically reversing pistons relieve the conveying system when blocked.
• Tough hopper with vibrator and grill designed for work with steel fibres.
• Centrally positioned lubrication point for easy service.
• Low weight is an advantage for transport.
