HONGDA S-valve serial high-pressure pumps,Z-gate-valve serial medium-pressure pumps and D-butterfly-valve serial low-pressure pumps are concrete transport equipments widely applied to such building projects as urban construction,bridge,power,and energy sources,etc. The machines adopt such world advanced techniques as open hydraulic loop,distribution valve auto-compensating clearance,constant power control, total hydraulic automatic change,and electric proportional control,etc., carried out deep and meticulous studies and experiments in many aspects like concrete piston self-lubricating,etc.,and has won many patents. HONGDA pump trailer is a new product at international level which is developed by combining latest technologies both at home and abroad. HONGDA pump trailer contains three series and more than twenty product types,and HONGDA is the professional producing base with most complete models and specifications in CHINA, which can fully meet various needs of all customers. HONGDA pump trailer all adopts steamline production assembly while the company strictly controls all the machining processes and assembly quality and gives final test to every pump trailer by simulation working conditions and overload experiments to ensure customers' zero fault in the first operation.
