SP/G pump with rotary drive

For multi-line lubrication systems

The SP/G rotary-drive piston pump for multi-line lubrication systems features a constant 33:1 gear ratio. Its compact design, with only two rotating/moving components, enables the pump to be driven by reciprocating motion and eliminates the need for elastomer seals, springs, or additional check valves. The SP/G pump is available as a self-priming pump or as a pump requiring inrush pressure. Versions with two or four outlets are available. The two-outlet version is available with two piston sizes to accommodate different delivery volumes. A single, vibration-resistant stroke adjustment screw, fitted to each pair of outlets, allows for precise piston stroke adjustment.

Technical characteristics and advantages

Virtually maintenance-free, vibration-resistant design for 24/7 operation
Designed for operation at high ambient temperatures and with all standard lubricating oils
Mechanical drive, no under- or over-lubrication
Oil is supplied from an oil sump or from an existing oil circulation system.
Adjustable performance
Available in two drive rotation direction options

Application areas

Marine industry; lubrication of intake valve seats of high-power four-stroke engines
General-purpose equipment with mechanical drive
