Heavy duty internal gear pump
max. 365 m³/h, max. 14 bar Viking Pump

The Universal Seal series pumps are similar to the Heavy Duty series, offering thrust control and adjustable rotor clearances to compensate for wear and viscosity.

An enlarged bearing housing at the rear of the pump provides easy drive-end access, and accepts various sealing options including:

packing
component mechanical seals
cartridge single-mechanical seals
cartridge double-mechanical seals, and
cartridge triple-lip seals.

This allows drive-end access for maintenance or replacement of cartridge seals without opening the head and pulling the rotor/shaft. Some sizes also offer behind-the-rotor component mechanical seals.

Ports are available in a variety of 90- and 180-degree configurations. Integral pressure relief valves are standard.
