PV2R Series Complete Guide: 21 Models Compared & Replacement Solutions (2026)

1. What is PV2R Series Vane Pump?

The PV2R series is a line of fixed displacement vane pumps originally developed by Yuken. Known for their high efficiency, low noise, and long service life, PV2R pumps have become the industry standard in injection molding, die casting, and industrial machinery.

Key design features of PV2R series:

• Cartridge design - Easy maintenance and repair
• Balanced vane configuration - Reduces wear and extends life
• High pressure capability - Up to 25MPa maximum pressure
• Multiple displacements - 21 models from 6cc to 153cc

2. Why Choose PV2R Series Vane Pumps?

PV2R series pumps are preferred by thousands of hydraulic system operators for several compelling reasons:

2.1 High Efficiency & Low Energy Consumption

PV2R pumps achieve volumetric efficiencies greater than 93%, significantly reducing energy costs compared to older or lower quality pumps. The balanced vane design minimizes friction losses while maintaining consistent output pressure.

2.2 Quiet Operation

With noise levels as low as 65dB under normal operating conditions, PV2R series pumps are ideal for factories that prioritize low-noise operation. The precision-machined components and optimized flow paths work together to reduce mechanical and fluid noise.

2.3 Long Service Life

Properly maintained PV2R pumps often exceed 20,000 operating hours. The cartridge design means that worn components can be replaced without removing the entire pump from the machine, significantly reducing maintenance downtime.

3. Complete 21 Models Comparison

The PV2R series is organized into three main families, each designed for different flow rate requirements:

4. PV2R1 Series Details (7 Models)

The PV2R1 series is ideal for small to medium-sized injection molding machines and compact industrial systems requiring lower flow rates.

5. PV2R2 Series Details (8 Models)

The PV2R2 series is the workhorse of the PV2R family, designed for medium to large injection molding machines with flow requirements in the 26-65 cc/rev range.

6. PV2R3 Series Details (6 Models)

The PV2R3 series delivers the highest flow rates in the PV2R family, designed for large injection molding machines and heavy-duty industrial systems.

7. Typical Applications

The PV2R series vane pumps are used in a wide range of industrial applications:

7.1 Injection Molding Machines

The most common application for PV2R pumps. Haitian MA600 to MA6000+ machines typically use PV2R1 series for small machines and PV2R3 for large ones.

7.2 Die Casting Machines

High pressure capabilities make PV2R series ideal for die casting applications requiring consistent pressure and reliability.

7.3 CNC Machining Centers

Low noise and high efficiency make PV2R pumps perfect for CNC machines where operator comfort matters.

7.4 Industrial Hydraulic Presses

The durability and reliability of PV2R pumps make them a top choice for hydraulic presses in manufacturing plants.

9. FAQs About PV2R Series

9.1 What is the expected lifespan of a PV2R pump?

With proper maintenance (regular oil changes, clean filters), PV2R series pumps typically last 20,000+ hours. Haichen replacement pumps come with a 12-month warranty covering materials and workmanship.

9.2 Can I replace just the cartridge on my existing pump?

Yes! The PV2R cartridge design makes this possible. Contact us for cartridge-only options if your housing is still in good condition.

9.3 How much oil does a PV2R pump require?

Recommended minimum reservoir capacity is approximately 5 times the flow rate in liters per minute. For example, a PV2R1-17 needs about 150-liter minimum capacity.

9.4 What oil should I use with PV2R pumps?

Use anti-wear hydraulic oil with ISO VG 32-46 viscosity. Operating temperature should stay within 30-55°C for maximum pump life.

9.5 How can I identify which PV2R model I have?

The model number is typically stamped on the pump housing. If not legible, measure the shaft diameter, mounting flange, and count the displacement for identification.
