This pump was introduced earlier than 1968, It is featured in my hydraulics book first edition 1967. Designed to use emulsion 95/5 (5% oil) and was 8.5 Imp GPM and worked @ 2000 psi at a motor speed of 1500 rpm. Pumps today operate at 5000 psi with a separate pump for positive set at 6000 psi based on mine geology.
