Hydraulic Pumps
At Star Hydraulics, we offer manually operated pumps in three types: single-piston, two-speed, and double-acting, along with models that include 4-way valves. Selecting the right pump depends on your specific application and how force is applied:
• Single-Piston or Double-Acting Pumps: Ideal for applications with a constant load, such as lifting or holding heavy weights.
• Two-Speed Pumps: Best when low resistance is followed by a need for high force, like presses. These pumps automatically switch from high-volume, low-pressure flow to high-pressure, lower-volume flow as needed.
• Pumps with 4-Way Valves: Designed for use with double-acting cylinders that need to exert force in both directions.
Reliable hydraulic pumps for manual hand or foot operation, available with or without built-in oil reservoirs and control valves. These single-stage pumps offer a simple solution for delivering constant low flow with high-pressure output.
Single Speed Pumps
Dual stage hydraulic pumps deliver rapid low-pressure movement and automatically shift to high pressure for full force. Designed for hand or foot operation, they are available with optional built-in oil reservoirs.
Two Speed Pumps
Compact double-acting pumps deliver oil on both forward and return strokes. Their lightweight design excludes a built-in oil reservoir, overload relief valve, and manual pressure release valve.
Double Acting Hydraulic Pumps
Deliver a low-cost, efficient way to manually generate or increase pressure in a hydraulic system. Designed to mount directly into a manifold block, these pumps provide reliable hydraulic power without the need for a costly valve body. They include suction and pressure check valves, but do not include release or overload valves.
Manifold Mount Pumps
Engineered for wire-line oil saver applications, these heavy-duty single-piston pumps feature a convenient pressure release valve, ensuring reliable manual operation on oil rigs.
Wire Line Oil Saver Piston Pumps
Star offers pumps with bronze or stainless steel wetted parts, providing corrosion resistance. For harsh environments, 100% stainless steel options are available to meet your specific requirements.
Stainless Steel Pumps
Designed for double-acting cylinders, these pumps use a 4-way valve to advance and retract at full pressure. Available on single-stage, dual-stage, and portable pumps.
Pumps with 4-Way Valves
Heavy-duty, all-steel oil reservoirs built for tough environments. Available in standard or custom lengths with mounting options to suit a wide range of applications.
Star Oil Reservoirs
Star offers a full range of high-quality pump accessories and custom options to meet specific hydraulic needs, including control valves, sight glasses, gauges, and fluid level indicators.
