Frequently Asked Questions (FAQ) About Piston Pumps
Piston pumps are the "heart" of hydraulic systems, offering unmatched power and versatility for moving fluids efficiently. Known for their high volumetric efficiency and durability, they are the go-to solution for industries ranging from agriculture to heavy manufacturing.
Below, you will find expert answers from Hayneks Hydraulic regarding selection, maintenance, technical specifications, and the differences between bent axis and swash plate designs. This guide is designed to help you choose the right pump and ensure long-lasting performance.

Question: What is a Piston Pump and why is it preferred?
A piston pump is a positive displacement pump that uses the reciprocating motion of pistons to move fluid. They are capable of generating high pressures (often exceeding 400 bar).
Due to their high volumetric efficiency and robust construction, they are the preferred choice for demanding applications like cranes, excavators, and industrial presses where reliability is paramount.
Question: Difference between Bent Axis and Swash Plate pumps?
These two types serve different needs:
- Bent Axis Pumps: Feature pistons at an angle to the drive shaft. They are compact, durable, and excellent for high-pressure mobile hydraulics.
- Swash Plate Pumps: Feature pistons parallel to the shaft. They often allow for variable displacement, offering precise flow control for industrial machinery.
Both types are available in Hayneks inventory to suit your specific application.
Question: How do they differ from Gear Pumps?
Gear pumps are typically used for lower pressure applications (max 250 bar). Piston pumps, however, can handle pressures up to 400-450 bar and offer superior efficiency (95%+). For heavy loads and precise operations, a piston pump is the superior choice.
Question: What should I consider when choosing a pump?
To ensure you select the correct pump, consider the following:
- Max Working Pressure: The bar rating your system requires.
- Flow Rate: The volume of fluid needed (L/min).
- Rotation Direction: Right (CW) or Left (CCW) based on your PTO output.
- Mounting Type: Connection standards (e.g., ISO flange).
Question: Can rotation direction be changed?
Most piston pumps come with a fixed rotation. However, on select Hayneks models, rotation can be reversed by adjusting the back plate. Caution: This requires technical expertise; incorrect adjustment can damage the shaft seal.
Question: Which hydraulic oil should be used?
For optimal performance, use high-quality hydraulic oils such as ISO VG 46 or ISO VG 68 with anti-wear additives. Keeping the oil clean and filtered is the single most important factor for pump longevity.
Question: Why is my pump overheating or making noise?
Excessive noise is often a sign of cavitation (air entering the system or a clogged suction filter). Overheating typically results from low oil levels, using the wrong viscosity oil, or internal leakage caused by component wear.
Question: What about maintenance and lifespan?
With proper lubrication (clean oil) and regular filter maintenance, piston pumps can provide years of reliable service. Preventing cavitation and monitoring oil temperature are key to extending the life of your pump.
