Compact and efficient, the Parker PD Series of Positive Displacement Open-Circuit Piston Pumps boosts productivity in medium pressure industrial applications. Featuring a rugged cradle-bearing design, wide temperature range, full power thru-drive capability and an optional torque limiter, industrial PD pumps ensure reliable performance and quick response. The series also utilizes unique “ripple chamber” technology to reduce pressure pulsations decreasing noise.
