grease pump / hand / piston / lubrication

The PMG hand pumps are intended for the provision of
grease lubrication systems where progressive dividers
are used. The pump body is made of light alloy and
houses the steel pumping piston operated by a vertical
lever. There is a lubricant tank at the top with relative
presser disk and, on model PMG-10, the compression
spring.
An adjustable safety valve protects the pump and the
components from overpressure. The lubricant leaking
from the valve indicates a system block.
