PVP series Hydraulic Piston Pump
The Parker PVP Series provides durable variable volume hydraulic piston pumps for medium pressure applications. With a pressure rating of 3,600 psi and a wide range of controls, PVP pumps are efficient and reliable.
The specifications of the Parker PVP series hydraulic piston pumps are as follows:
I. Displacement and Models
Displacement range: 16 to 140 ml/rev. Specific models include PVP016, PVP023, PVP033, PVP041, PVP048, PVP060, PVP076, PVP100, and PVP140.
II. Pressure Parameters
Rated operating pressure: 250 bar (some models can reach a peak pressure of 350 bar, but specific model numbers must be confirmed).
Inlet pressure: Minimum 0.8 bar, maximum 0.7 bar (please consult when using high-pressure water-based media).
Controlled leak pressure: 7 bar (100 PSI).
III. Speed and Performance
Minimum speed: 500 rpm (some models can reach 300 rpm).
Maximum speed: Some models can reach 3000 rpm.
Efficiency:
Volumetric efficiency: Because the piston pump has a continuous sealing line within its working volume, it achieves high volumetric efficiency. Mechanical Efficiency: Excellent lubrication between all moving parts results in high mechanical efficiency.
Overall Efficiency: High overall efficiency is achieved near the rated operating point.
IV. Control Methods
Pressure Compensation: Automatically adjusts output pressure to prevent overload.
Remote Pressure Compensation: Supports remote signal pressure control.
Load Sensing: Adjusts flow rate based on load demand to improve energy efficiency.
Power (Torque) Limiting: Limits maximum system power to protect equipment.
Electro-hydraulic Proportional/Servo Control: Enables high-precision flow and pressure regulation.
Low-Pressure Standby: Reduces no-load energy consumption.
V. Typical Application Scenarios
Industrial Hydraulic Systems: Suitable for high-pressure applications such as mining equipment and special machinery.
Engineering Machinery: Suitable for applications requiring efficient power transmission, such as construction machinery and agricultural equipment.
High Dynamic Control: Modular compensators enable fast response and adaptability to load changes.
Process steps：
Customer inquiry: Customers will make inquiries before placing an order to understand product details and communication needs.
Quotation: According to customer needs, provide a formal quotation, including the name, model, quantity, delivery time, payment method, etc. of the goods.
Order confirmation: After the customer confirms the quotation, a formal purchase order will be placed.
Confirm the delivery time: communicate the delivery time with the production department, inform the factory of the order details, and arrange the production plan.
Sign an export contract: After the two parties confirm that it is correct, sign an export contract to establish a trade relationship.
Implement the letter of credit (if applicable): If the payment method of the letter of credit is used, the customer needs to be urged to issue the certificate and review the contents of the letter of credit.
Export stocking: According to the requirements of the contract and the letter of credit, arrange production, purchase raw materials and packaging, and prepare the goods.
Chartering and booking: Contact the freight forwarder to make a booking and arrange the transportation of goods.
Export inspection: Apply to the quality inspection department for export commodity inspection and provide relevant documents.
Apply for a write-off slip: apply for a write-off slip from the foreign exchange management department for subsequent foreign exchange write-off.
Export declaration: Declare exports to the customs and provide documents such as power of attorney for customs declaration, customs declaration form for export goods, commercial invoice, packing list, etc.
