Small footprint, big benefits with new vertical pump

The CombiProLine OH3 offers a space saving of up to 70% when compared to the equivalent OH2 horizontal pump. By eliminating the need for a baseplate, the CombiProLine is easier to install than horizontal pumps and offers a weight advantage that makes it particularly attractive for platform installations.

CombiProLine OH3 pumps can be used to move thin, clean or slightly polluted liquids as well as non-viscous and light viscous liquids at up to 300mm2 per second. Typical examples include offshore installations and crude oil extraction, petroleum refining and distribution, processing of hydrocarbons (such as butane and acetylene) and gas processing, including methane, butane, LNG and LPG. Its combination of space-saving and performance parameters also offer benefits in water treatment and general industrial liquids handling applications.

Part of SPX Flow’s Johnson Pump Combipro family of heavy duty centrifugal pumps, the OH3 is designed and built to deliver long life and reliability in the harshest environments and meets the requirements of API 610 and ISO 13709.

CombiPro pumps feature a number of innovative design elements to prolong their working life and make maintenance simpler. For example, a robust, metal-to-metal fit between the pump cover and casing is assured using a special gasket to ensure proper sealing and alignment. An oil-lubricated bearing arrangement ensures smooth operation, with the option of cooling the oil bath in high temperature applications.

Disassembly and assembly of the bearing section and the complete rotor set can be undertaken without the need to remove either the motor or pump and without disconnecting the pipes, minimising downtime. A further benefit is the standardisation of parts, which offers high interchangeability across the Combipro range and greatly reduces spare parts holding for SPX Flow customers. It also means there are fewer variants to remember, making maintenance crew training much simpler.

Standard specification CombiProLine OH3 pumps are available for quick delivery. Customised models to accommodate lower or higher temperature variants, or other application-specific parameters, can be made on request but are subject to longer lead-in times.
