OTC Dual Master Jr. 2-Speed Hand Pumps

The OTC Dual Master Jr. 2-speed hand pumps offer a blend of speed, versatility, and safety, making it a valuable tool for a variety of hydraulic tasks requiring efficient and controlled pressure application. The two-stage design provides both high-volume at low-pressure for rapid ram approach and return, and then automatically switches to a low-volume at high-pressure (up to 10,000 psi) for heavy lifting applications. This allows this OTC hand pump model to handle a wider range of tasks than single-stage pumps. The hand pumps are available in two versions, the 4016 model with a 2-way valve for single-acting rams and the 4017 model with a 4-way valve for double-acting rams, increasing the pump's applicability. Choose the hand pump that is better suited for your application needs.
