Piston-type hand pumps offer completely self-contained units for instant operation. Each pump consists of a pre-filled oil reservoir, pump head with external load release valve, and an operating lever. The two-speed model HP227 (807-895) enables rapid cylinder rod advancement until load contact, and then slows as the lift begins. Each pump is compatible with our range of high-pressure cylinders, and can operate one or more cylinders dependant on pump usable oil capacity and cylinder oil capacity. Each pump is tested to 125% of its working pressure and is issued with a manufacturers test certificate and instruction leaflet. The outlet connection is 3/8in. NPTF.
