The Denison PV/PVT series piston pump is an axial variable displacement piston pump suitable for open circuits, with high economic efficiency. It is a high-power hydraulic pump that can operate continuously in various environments. This article not only summarizes the information of the Denison PV/PVT series piston pump, but also includes a lot of data that must be installed and executed during operation. These data are very important, This is the key to determining whether a pump can continue to operate efficiently.
Introduction to PV-PVT series plunger pumps that must be understood:
The PV/PVT series hydraulic pump is an axial piston variable displacement hydraulic pump suitable for open circuits, and its design focuses on the economy of operation. The PVT series is a derivative series of PV pumps with rear drive and side oil port configuration.
The displacement range of the PV/PVT series plunger pump is 14.4 to 130.0ml/rev (0.88 to 7.93 in'rev), with a continuous working pressure of 280 bar (4000 psi). The variable forms include: pressure compensation (constant pressure) variable, pressure compensation variable with pressure control port, load sensing variable, and torque limit (equivalent to constant power) variable.
The PV/PVT series hydraulic pumps have been widely used in high-pressure and industrial fields with variable requirements, and their prices are very competitive.
Install;
This series of hydraulic pumps is designed to operate in any installation posture, and its mounting flange and two hole mounting flange fully comply with SAE standards. During installation, it is necessary to ensure the coaxiality between the pump's transmission shaft and the drive shaft of the prime mover. A dial gauge should be used for inspection: the corresponding installation positioning hole must be concentric with the coupling, which is particularly important for rigid connection installation without the use of elastic couplings.
There are some common pump model:
PVT102L1EC03AA0, PVT102R1EC03AA0, PVT102R1EC04AB0, PVT102R1EF04BB0, PVT102R1EJ04S00
PVT102R1EL03S00, PVT102R1EW03S00, PVT151L1EC04BB0, PVT151L1EF04BB0, PVT151R1EC03AA0
PVT151R1EL03AA0, PVT152R1EC03S00, PVT152R1EC04AA0, PVT152R1EF03BB0, PVT152R1EK04S00
Rear drive
Installation dimensions of the rear drive section; There are two types of shaft extensions available with SAE standard splines and flat keys. For size parameters, please refer to the "Installation Diagram of Denison PV | PVT Series Plunger Pump"
Spline: When installed with a bracket, the allowable coaxiality deviation (reading difference on the dial gauge) of the drive shaft is 0.06mm (0.002in). When installed with a flange, it is 0.03mm (0.001in). The inclination deviation between the spline shaft and the spline hole relative to the positioning surface should be less than ± 0.002 mm/mm (± 0.002 in/in): The spline hole should meet the side fit and level 5 accuracy requirements specified in SAE-J498c, and the heat treatment hardness should be RCc27-34.
The joint surface of the coupling must be lubricated, and it is recommended to use lithium molybdenum disulfide or similar lubricating grease.
Ping Jian: High strength keys must be used, with a heat treatment hardness of Rc27-34. The edges should be chamfered 0.75-1 (0.03-0.04) x 45 "to eliminate the influence of rounded corners on the bottom edge of the keyway.
Must understand PV-PVT series plunger pump lateral bearing capacity:
The PV series plunger pump is designed to be driven axially. It is recommended that the transmission shaft should not bear lateral loads. If lateral loads are unavoidable, please consult our company, Elephant Hydraulic.
Bearing lifespan: Please refer to the Technical Parameters Table for Each Model of Denison PV/PVT Series Plunger Pump
piping
The shell pressure should not be higher than the suction pressure by 0.9 bar (15 psi). Before connecting the shell oil discharge pipeline to the oil tank, some of the pipelines should be higher than the high liquid level of the oil tank and connected to the oil tank at a point lower than the liquid level. The connection point should be as far away as possible from the pump's suction port. All pipelines, whether hard or soft, should have corresponding diameters and strengths to ensure that the fluid flow can freely flow through the hydraulic pump. If the diameter of the suction pipeline is too small, the hydraulic pump cannot operate at the rated full speed; and if the diameter of the outlet is too small, it will generate back pressure and cause heating.
It is recommended to use flexible hose connections. If a rigid pipeline connection is used, the piping work should be done accurately to reduce the connection stress between the hydraulic pump and the pipeline. Sharp bending of pipelines should be avoided as much as possible. All pipelines of the system should be cleaned with solvents before installing the hydraulic pump, and the entire hydraulic system should be confirmed to be free of dust particles, fabric fibers, oxide skin, and other foreign impurities.

Attention: Do not use galvanized pipes, as the galvanized layer may peel off during continuous use.
Oil viscosity and viscosity index
This series of PV/PVT plunger pumps recommends using petroleum based hydraulic fluids that comply with the Denison specification HF-1 and contain antioxidants, corrosion inhibitors, and defoamers: hydraulic fluids with anti-wear agents added.

The high viscosity during cold automatic operation is -1600 cSt (7500 SUS}), which should be a low-pressure, low flow condition. If possible, the engine should be started at a low speed;
Zui high viscosity, full power condition -160 cSt (750 SUS)
Excellent viscosity, long service life -30 cSt (140 SUS);
Zui low viscosity, full power condition -10 cSt (60 SUS)
Viscosity index - Zui low 90V I. A higher oil viscosity index can expand the operating temperature range, but may shorten the service life of the oil.

Maintenance of PV-PVT series plunger pumps that must be understood:
This series of hydraulic pumps has self-lubricating function, and the maintenance required is only protective. As long as the filter element of the hydraulic system is frequently replaced to keep the working fluid clean, all pipe fittings and screws of the system should be kept tight. The hydraulic pump should not operate under pressure or speed exceeding the recommended range.
If the hydraulic pump runs abnormally, it can be disassembled for inspection, but the troubleshooting table should be consulted before disassembly. The maintenance work can be carried out according to the process of disassembling, repairing or replacing faulty parts, and reassembling.
Oil cleanliness
Before and during continuous operation, an oil filter should be used to clean the working oil, ensuring that the solid particle contamination level of the oil is not higher than ISO17/14, which corresponds to level 8 of NAS1638 (level 9 for particles not larger than 15um). Usually, using a filter with a filtration accuracy of 10um can meet this requirement for oil cleanliness. Good oil cleanliness can effectively extend the service life of hydraulic components. The invasion and generation of pollutants vary under different application conditions. Therefore, specific analysis should be conducted on the pollution situation under actual operating conditions to determine the corresponding filtration method to meet the requirements of maintaining oil cleanliness.
