The R pump is ideal for the type of application where the metal rotored pump will not work effectively. When you need to strip clean your pump because the product will not wash out by using a normal CIP process such as meat processing, the R pump overcomes this problem by its simple robust design. The R pump design utilises a floating rotor without rotor nuts. Rotors are interchangeable and can only be fitted in one position due to a specially modified square shaft.

This simple and robust design allows for all sanitary parts to be changed in minutes without removing the pump from the line. The pumps are now fitted with an ‘O’ ring front cover gasket, making the routine maintenance even easier.

SPX uses multi-lobe rubber rotors (twin lobe on the RO) as standard. These deliver very high efficiency for the handling of a wide range of difficult and abrasive products.

As a strip clean unit the simple rubber lip seal is front loaded for easy replacement.

For special applications a range of metal or plastic rotors in several different profiles can be supplied, which are ideal for abrasive or corrosive products.

R pumps can be fitted with enlarged rectangular inlets for metal and dough slurries. Additionally, if entrapped air is a problem, special de-gassing front covers can be used, enabling entrapped air to be removed prior to cooking or processing. If you have a problem with fitting a pump beneath your tank or hopper a front cover outlet can be supplied. For higher discharge applications a cover with outrigger bearings is available.

Pumps can be supplied with a variety of drive units, or complete with hoppers or auger feed units.
