HP4VG Series Axial Piston Variable Displacement Hydraulic Pump Advantages:
• The swash plate is designed with an axial piston variable pump for closed-circuit hydrostatic transmission.
• When the swash plate passes the neutral position, the flow direction of the hydraulic oil will change smoothly.
• Two pressure relief valves are installed on the high-pressure side to prevent overload.
• The built-in charge pump acts as a charge pump and control.
• The built-in low-pressure relief valve limits the maximum charge pressure.
• Brand new slewing components and bearings improve the transmission efficiency and the input speed.
• One-piece design at the rear of the shell reduces leakage points.
• Optimized shell design to reduce vibration and noise.
• Electric proportional displacement control to meet the application requirements of multiple industries.
• 45° oil outlet design to optimize pipeline connection.
• Optional flush valve, directly installed on the pump body.

¿Cómo encontrar un kit de juntas para un cilindro hidráulico?
Finding the appropriate seal kit for a hydraulic cylinder involves a few steps. Follow this guide to help you locate the suitable seal kit for your specific hydraulic cylinder:
- Gather Information: Before starting your search, gather essential information about the hydraulic cylinder. This includes the cylinder’s make, model, and any identifying serial numbers or part numbers. Note down the dimensions of the cylinder, such as the bore diameter, rod diameter, and stroke length. Having these details readily available will make finding the correct seal kit easier.
- Manufacturer’s Resources: Begin your search by checking the manufacturer’s resources. Visit the manufacturer’s website or contact customer support to explore if they offer seal kits specifically designed for your hydraulic cylinder. Many manufacturers provide detailed product catalogs, parts lists, or online search tools to help customers find the appropriate seal kits.
- Online Suppliers: Look for reputable suppliers specializing in hydraulic seals and seal kits. Use search engines or online marketplaces to find suppliers that offer a wide range of hydraulic seal kits. Some popular suppliers include hydraulic component distributors, industrial supply companies, and specialized hydraulic seal manufacturers. Make sure to filter your search results based on your cylinder’s make, model, and dimensions to narrow down the options.
- Seal Kit Specifications: Once you identify potential seal kits, review their specifications and compare them to the information you gathered about your hydraulic cylinder. Check if the seal kit includes all the necessary seals, such as rod seals, piston seals, and gland seals. Verify that the dimensions and specifications of the seals match those of your cylinder.
- Guías de referencia cruzada: Some suppliers or manufacturers provide cross-reference guides or compatibility charts to assist in finding the right seal kit. These guides allow you to match your cylinder’s part numbers or specifications with the corresponding seal kit. Consult these resources if available to ensure an accurate match.
