HVN Double Suction, Heavy Duty API 610 Process Pump (BB2) Casing and cover are holding the amply designed stuffing box room. The corrosion allowance for the wall thickness of carbon steel casings and casing covers is 3.2 mm or more. The HVN range is characterized by the use of robust and modular design elements to reduce the number of parts. Pump Test Pressure The casting is tested at 1.5 times the value of the maximum discharge pressure. Higher test pressures on special request. Wear Rings All HVN pumps are equipped with casing and impeller wear rings. The clearances are in accordance with API...

HVN Double Suction, Heavy Duty API 610 Process Pump (BB2) Economical and Energy Saving Hydraulics The hydraulics of the HVN pumps are designed and built in accordance with the lastest level of knowledge. In extensive research, test and development programs, the shape of the impellers and volute casings were optimized with regard to the flow dynamics. The single piece, closed impellers are of an extremely high accuracy in shape and surface finish with special features to achieve very good properties in case of variation of impeller diameters. The high efficiencies over a wide flow range results...

HVN Double Suction, Heavy Duty API 610 Process Pump (BB2) HVN Design Coupling, coupling Guard Pumps and drivers are usually connected by flexible disc couplings. The spacer length is dimensioned to allow a trouble free removal of mechanical seal. The standard coupling guards are made inf AIMg perforated sheet metal. The two piece rectangular shaped guards are built to withstand forces up to 200kg. Special guard designs and material are available. Direction of rotation The normal rotating direction is preferably counter-clockwise (ccw) viewed from the driver end. HVN 6x17/ 16x26/ 18x30 are running...

HVN Double Suction, Heavy Duty API 610 Process Pump (BB2) Performance Curves HVN pumps have stable characteristics. They can run continuously in the operating range from minimum flow (Qmin) to maximum flow provided that enough NPSH is available. HVN pumps can be operated at a wide range of speeds. For speeds higher than 3600 rpm, the smooth function has to be checked by the factory. The pump hydraulics are based on a kinematic viscosity of 1mm/s. For higher viscosities, correction factors are to be considered if applicable. Materials of Construction MATERIAL TABLE Material classic API 610 Material...

Characteristics & Design Features 2 More than 30 radially split puma casing sizes centerline mounted. Suction and discharge branches are arranged top-top. Discharge Branch sizes ranking from 4” to 20”. 11 Sleeve and tilting pad bearing also possible on request. 12 Due to the top-top arrangement of the suction and discharge branches, inspection and maintenance of the HVN pumps do not present any problems. When the rotor is dismantled, the pump casing remains on the baseplate connected to all piping. 13 1 Pressurized casing components are subject to intensive control by the highly efficient quality...
