Magister Hydraulics 5 Qt Double Acting Pump
The Magister Hydraulics 5 Qt pump delivers 1.5 CID displacement with a 3600 PSI rating. Its 5-quart steel reservoir features corrosion-resistant construction for long-term reliability. The unit supports a true double-acting workflow, pushing and pulling the handle to power a double-acting cylinder, which reduces cycle times in maintenance and testing tasks. The changeover valve allows quick switching between quick operation and controlled flow. Ports are 3/8″ NPTF to fit standard hydraulic fittings. Suitable for high-pressure applications requiring compact yet robust amplification of force.
Chief Hydraulic Hand Pump — Double-Acting
The Chief hydraulic hand pump is a portable double-acting unit weighing about 20 pounds, designed for fieldwork and tight spaces. It provides steady fluid flow through either single- or double-acting lever configurations, making it versatile for cylinder operation, line bleeding, and valve testing without electricity or air sources. Its 1.3-gallon reservoir and 3/8″ NPT port support standard hydraulic setups, with CID displacement at 1.51 cubic inches per full stroke. The compact dimensions enable use in remote locations where power access is limited.
Magister Hydraulics 3 Qt Double Acting Pump
This Magister unit uses a 3-quart reservoir with a 1.5 CID working volume and 3600 PSI maximum. Its compact vertical tank design and corrosion-resistant steel construction deliver durability in workshop and field environments. With a true double-acting mechanism, both strokes contribute to fluid displacement, speeding up operations for cylinder actuation or system testing. 3/8″ NPTF ports ensure compatibility with common hydraulic hoses and adapters, making it suitable for standard maintenance tasks and equipment testing scenarios.
Magister Hydraulics 5 Qt 2.7 CID Pump
The 5 Qt Magister model with 2.7 CID offers higher displacement per stroke, enabling faster actuation in demanding applications. With 3600 PSI capability and 3/8″ NPTF ports, it maintains compatibility with standard hydraulic accessories. Its steel reservoir and changeover valve support easy switching between rapid pumping and controlled flow modes. This pump is designed for power users who regularly operate larger double-acting cylinders or require quick reservoir emptying and refilling during extended testing sequences.
Spare Parts Holland 2.7 CID 1 Quart Pump
The Spare Parts Holland pump features a cast iron monoblock body with a chrome-plated steel rod and a long steel handle for maximum leverage. It displaces 2.7 CID and can reach up to 4100 PSI, with an optimal working pressure around 1200 PSI for efficient operation. The unit includes a 1-quart oil tank and 3/8″ NPTF ports, making it compatible with standard hydraulic systems. Its compact, wall-mountable design supports workshop optimization and quick access in maintenance bays.
Buying Guide
- Displacement and cycle speed: Higher CID means more fluid moved per stroke, reducing cycle times for large cylinders. Consider models with 2.7 CID or 1.5 CID depending on cylinder size.
- Reservoir capacity: Larger tanks (3–5 quarts) reduce refill frequency during extended use; smaller tanks are lighter and easier to maneuver.
- PSI rating: Match the pump’s pressure limit to your cylinder and system requirements. Higher PSI supports tougher seals and thicker actuators.
- Ports and fittings: Ensure 3/8″ NPT or NPTF ports align with your hoses and valves. Check for compatibility with common fittings and adapters.
- Portability and mounting: For fieldwork, prioritize lighter units with carrying handles. For workshops, consider wall-mountable designs.
- Durability: Look for corrosion-resistant reservoirs and a robust steel or cast iron body to withstand frequent use and exposure to hydraulic fluid.
- Valve operation: Double-acting pumps offer fluid displacement on both strokes, increasing efficiency. Changeover valves allow quick mode switching when needed.
- Maintenance access: Consider units with straightforward seal replacements and accessible reservoirs to minimize downtime.
- Application fit: If you operate smaller test rigs or bleed lines, a compact 3 Qt unit may be ideal; for heavy maintenance or high-flow testing, a 5 Qt or higher CID model is preferable.
- Safety: Verify that the system includes proper relief or safety features and that the unit is compatible with your existing hydraulic system pressure.
