Multistage Centrifugal High Pressure Pumps

Designed for the transfer of hydrocarbons and pure corrosive liquids.

Main features:

• Modular principle (convenient for supply with spare parts)
• Greater durability due to durable performance
• Compensation of axial shear by piston and disc discharge
• Any shaft seal, optional design with cooling
• Low NPSH values, optional version with inducer
• Suction housing design: the arrangement of the nozzles as a standard can be changed to any position
• Operation in inconvenient conditions for liquid inflow due to topping NPSH Impeller
• High strength due to large-sized bearings

Operating parameters
DN: 32 – 200 mm
PN: 160 bar max
Q: 500 m³/h max
H: 1600 m max

Possible designs:

• Horizontal installation on legs, different arrangement of nozzles
• With suspension in the middle for high temperature of the medium
• With NPSH Impeller and axial inlet
• With magnetic clutch, special version for use with hot water
• Vertical space-saving insallation

Centrifugal Vertical Barrel Pumps

Centrifugal vertical barrel pumps are used where stable pumping parameters must be achieved at low feed heights.

Pumped liquid:

• Condensate in power plants and in heating systems
• Hydrocarbons in the chemical industry and petroleum engineering
• With magnetic coupling, special version for use with hot water
• Slightly aggressive water in the concentration plants.

Operating parameters:
DN: 32 – 200 mm
PN: 100 bar max
Q: 500 m³/h max
H: 400 m max

Shaft sealing:
Shaft sealing is performed in accordance with the operating conditions by means of mechanical seals or stuffing box packing. The cartridge seal is optionally available.
