4535V Double Vane Pump (172 bar) — Ultra-High Flow | Hydraulic Pump Specialized for Heavy-Duty Industrial Presses

Jinpinlub HYD — Thu, 30 Apr 2026 21:02:06 +0000

Особенность

The 4535V Double Vane Pump is able to produce a maximum of 172 bars of hydraulic pressure. It has two cartridges (the 45V and 35V) that can deliver an extremely high flow of fluid. The 4535V over standard hydraulic pumps are as follows:
1. High Maintainability: Because of the two-cartridge design, and unlike standard fixed displacement vane pumps, there’s no need for disassembly of housing and/or hydraulic tubes to rebuild the unit during maintenance. Rebuilding can be accomplished in a few minutes, simply by changing out the cartridges.
2. Long Service Life due to “Vane-in-Vane” Technology: The “vane-in-vane” design greatly reduces friction caused by high-pressure operation compared to either gear-type or standard vane pumps, resulting in an extended service interval.
3. High Flow and Quiet Operation: The performance of the 4535V is also quiet; it has a noise reduction capability that greatly exceeds that of piston-type pumps that have similar performance specifications.

Приложение

The 4535V Double Vane Pump is a great product due to its ultra-high flows, high-pressure capabilities, and dual circuit operation. Its uses include:
1.Large Scale Injection Moulding and Rubber Machines: The combination of both pumps produces greater flow, allowing for fast mould closing; thus, the majority of flow comes from this pump in the production process of many large injection moulding machines.
2.Heavy Metal Extrusion and Pressing Machines: The vanes of both pumps can withstand frequent shocks of high pressure, allowing for consistently smooth and efficient extrusion during high demand processes.
3.Die Casting and Metal Processing Equipment: Its design allows for quick maintenance by replacing the cartridge without removing any hydraulic lines, minimizing losses due to downtime in large mass production.

Equivalent to Vickers 2520V Double Vane Pump 172 bar supports high low voltage combined circuit output, movement is replaceable

Jinpinlub HYD — Thu, 30 Apr 2026 19:41:24 +0000

Особенность

The 2520V is a dual vane pump, capable of low noise operation. It combines the 25V and 20V pumps into one with a maximum rated working pressure of 172 bar. The 2520V is an ideal power unit for multi-functional hydraulic systems. The core advantages are as follows:
1. Two independent circuits can be powered by one shaft using either high or low – flow for each.
2. The Mother-Daughter design means that the amount of wear experienced by the stator is reduced, and will be far less than normal vanes over time.
3. Extremely quick to perform maintenance, as there is no need to disassemble the unit (due to plug-in design for both sides). Ideally suited for powering multiple functions from one hydraulic system.

Приложение

The double-vane pump 2520V has dual applications of high and low flow circulation, as well as a dual pump system, and can be maintained by a mobile worker. Mainly used in:
1.Injection Molding Machines and Rubber Molding Machines – Injection Molding Machines typically require a high flow/fast forward and low flow/high pressure to hold in place. The 2520V’s dual-piston structure can provide both types of flow and is the best solution for providing flow rates to match the combined high and low pressure circuits from one pump head.
2.Die-Casting Machines and Heavy Duty Hydraulic Power Supply Stations – Die Casting Applications have harsh environments and are generally operated continuously. The 2520V has a unique mother-in-the-line blade technology that provides excellent resistance to the effects of high pressure impacts, and because of the double-piston design, once the pump has worn out, only the internal components will need to be replaced at the site of the pump, thus avoiding disassembly of the complex and time-consuming line disassembly and ensuring the production line remains continuous.

35V vane pump Large displacement high volumetric efficiency for Injection molding machines Die casting machines

Jinpinlub HYD — Thu, 30 Apr 2026 18:35:11 +0000

Особенность

The 35V is a high-performance vane pump capable of withstanding pressure levels up to 172 bar (2500 psi). In comparison to the 25V, the 35V has a bigger displacement and thus is able to deliver even stronger power for heavy machine tools and large injection molding machines.
Mainly, it is characterized by:
1. Mother-and-daughter blade technology: Not only does it cut down the stator wear via pressure balancing, but it also runs longer at high pressure.
2. Movement-type structure: Enables changing of the movement part only without the need to open the pump casing, which significantly reduces the downtime and the maintenance time.
3. Silent and stable: Due to the multi-blade design, the pump produces very low noise and low pulsation even at large flow rates while, on the other hand, enhancement in stability is achieved.

Приложение

35V hydraulic pumps have the inherent advantages of large displacement, high pressure, and a movement design, so they have been very popular in the following areas:
1. Heavy-duty injection and blow molding machinery:35V delivers a larger flow output in comparison to 25V. When coupled with the high-pressure resistance of mother-in-line blades, it can satisfy the requirements of fast mold closing and high-pressure holding of large molds. Besides, the low-noise features can greatly enhance the workshop environment.
2. Large industrial presses and shear equipment:They are usually operated frequently and are also heavily loaded. The movement type design of the 35V pump can offer outstanding advantages. When wear happens, the movement can be very quickly replaced on site in order to restart production, which largely decreases the downtime losses of large production lines.
3. Metal forming and precision machine tools:The processing of machine tools demands very high dynamic stability. Since 35V can have extremely low flow pulsation, it can guarantee the smooth operation of hydraulic actuators, which, in turn, helps in producing better surface finishes and more accurate dimensions in metal cutting or forming.

Alternative to Vickers 25V Single Vane Pump Max 172 bar / 2500 psi, Used in industrial hydraulic systems

Jinpinlub HYD — Thu, 30 Apr 2026 17:42:50 +0000

Особенность

25V is the benchmark for industrial-grade vane pumps. It mainly focuses on parent-child blade technology allowing the pump to provide a high pressure of up to 172bar and a very long life by lowering the friction between the blades and the stator.
Among its advantages are:
1. Movement Design: An independent movement containing all the internal components was created, which even allows quick maintenance of the pump without dismantling it, which is really efficient in terms of maintenance compared to other similar pumps.
2. Superior Quietness: the pulsation of the 12-vane structure is so low that it is less noisy than traditional vane pumps.
3. Good compatibility: It will still hold a high volumetric efficiency even at high speed and high pressure, plus its reliability is much better that it of regular vane pumps.

Приложение

The 25V single vane pump boasts features of exceptional high-pressure resistance, low noise, and easy maintenance (moving structure). Its major application areas are as follows:
1. Injection molding machinery: A consistent high-pressure supply is necessary during the mold closing and high-pressure injection phases. The 25V primary and secondary blade layout can simultaneously provide continuous high-voltage output with minimal wear. Besides, its low noise feature can remarkably raise the factory work environment comfort level.
2. Die-casting and pressure machinery: Such equipment is most of the time run continuously and the working conditions are quite tough. The 25V moving design makes it possible to replace wearing parts swiftly without disconnecting the pump body from the pipeline, thus reducing downtime-related production losses to a minimum.
3. Metal cutting machine tools and automated production lines: To maintain the processing precision, machine tools need an extremely stable flow of output. The flow pulsation of 25V is so low that it guarantees the smoothness of the actuating element movement. Also, its high volumetric efficiency contributes to lowering the energy consumption of the entire system.
