The Haskel DSTV-122 is a powerful 2 HP single-air-head pneumatic pump that delivers hydraulic pressures up to 15,000 psi using clean compressed air ideal for spark-sensitive environments. With a nominal 122:1 ratio (actual ~130:1), this pump provides reliable, controlled fluid delivery for hydrostatic testing, calibration, clamping, and bolting. Its distance-piece design includes a stall-and-hold feature, allowing the pump to maintain pressure without continuous airflow. Constructed from stainless steel with UHMWPE dynamic seals, the DSTV-122 is durable and compact, making it well-suited for industrial and field applications.
