Model 283167 pump includes air motor, relief valve, clear reservoir with filler neck, strainer and 1200 psi safety relief device (82 bar). This is a pneumatically driven reciprocating piston pump. A changeover valve controls the pump's reciprocating motion (discharging oil to the outlet during the forward stroke and drawing oil in during the return stroke). The reciprocating pump operates under air pressure and therefore pumps lubricant until the required oil pressure in the system is reached.

Pump shutoff and monitoring must be initiated using a pressure switch and a 3/2-way pneumatic valve—these components limit and regulate the operating air pressure. These components must be installed at the user's site.
