Denison PV29 Piston Pump
- Variable Size Modification: The pump's maximum volume can be adjusted to match the needs of any particular application.
- Quick Response Compensator: The pump is fitted with a rapid response compensator, which has an off-stroke duration of 50 milliseconds and an on-stroke duration of 120 milliseconds. Other control alternatives are a ventable compensator, load sensing, and a power limiter.
- Changeable Port Plate: One of its parts includes a port plate that can be replaced to reduce maintenance costs and increase its operational life.
- Silent Working Environment: This feature ensures quietness during operation, hence reducing noise levels at work, which in turn improves working conditions because people can communicate without shouting over machines or background sounds. Also, it provides softer power delivery due to the nine piston rotating group design, thereby making the job site more conducive to concentration while working with such equipment.
- Tunable Compensator: By adjusting the compensators, users can achieve accurate control of output and performance of this device.
- Standard Shafts for Industries: Keyed shafts conforming to industrial standards have been employed in the manufacturing process to make them compatible with other pumps and easily replaceable when necessary, thus saving time during repairs or replacements.
- SAE Mounting System: It can be mounted interchangeably with other pumps having SAE mounts hence making installation flexible where different types need to be used together within same hydraulic system setup; also simplifies maintenance since all units share common mounting points which allows easy access during service procedures even if some components require removal before reaching others located beneath them
- Different Fluid Compatibility: It is designed for use with various kinds of hydraulic fluids, including fire-resistant types, thereby improving safety in different applications where flammability may pose hazards.


Denison PVT38 Piston Pump
- Variable displacement: The PVT38 is designed to perform full economic operation as an open-circuit piston pump while being suitable for use in different high-pressure and variable-flow industrial applications.
- High Pressure Capability: The pump can continuously operate at up to 4000 psi (280 bar) and handle intermittent pressures of 4500 psi (310 bar), thus ensuring reliable performance under tough conditions.
- Fast Compensator Response: With a fast compensator response time of 50 ms off-stroke and 120 ms on-stroke, the PVT38 delivers quick-response pressure control for efficient work with minimal pressure overshoot or undershoot.
- Quiet Operation: It runs quietly thereby reducing noise levels that may affect productivity or comfort within work places hence creating conducive environments for workers.
- High Contamination Tolerance: This pump has a very high contamination tolerance, which makes it more reliable and durable even when used in areas with dirty fluids.
- Maximum Volume Adjustment: The PVT38 provides the flexibility required by flow controls for maximum volume adjustment. Specific application demands can be met through this feature alone.
- Interchangeable Mounting: SAE mounting standards conformity enables easy interchange ability between other SAE mounted pumps during installation replacements will also become simpler because of this aspect too.
- Multiple Control Options: Various control options such as; a pressure compensator, ventable compensator, load sensing power limit control can be fitted onto the pump making it versatile enough to meet different needs of hydraulic systems.
