Product Overview
▔▔
The Voith IPVP series represents a specialized line of high-pressure internal gear pumps designed explicitly for variable-speed drives. Unlike standard hydraulic pumps that run at a constant speed and bypass excess oil, the IPVP series operates in harmony with variable-frequency drives (VFDs) and servo motors.
Key Advantages
▔▔
- Radial and Axial Compensation: The pump utilizes floating axial plates and a flexible filler piece mechanism. As hydraulic pressure rises, these components are pressed tighter against the sides and tips of the gear teeth, keeping internal gaps at a bare minimum.
- Low Noise Emission: Because the gear teeth mesh smoothly and the internal fluid paths are optimized, the acoustic output is remarkably low. This helps factories meet strict workspace noise regulations without building expensive sound-proof enclosures.
- Variable Speed Optimization: The internal intake ports are wider and reshaped to prevent cavitation when the pump rapidly accelerates from zero to maximum RPM. This makes it an ideal match for dynamic servo-drive systems.
- Multi-Flow Capability: If your machinery requires multiple independent hydraulic circuits, several IPVP pumps can be combined onto a single drive shaft, saving space and reducing installation costs.

FAQ
▔▔
What is the main difference between a standard Voith IPV pump and an IPVP pump?
The primary difference lies in the intended drive system. The standard IPV pump is optimized for traditional constant-speed electric motors. The IPVP series is specially modified with optimized internal fluid channels and port geometries to handle the rapid speed changes, deceleration, and reversing cycles typical of servo-driven or variable-speed motor setups.
Can a Voith IPVP pump run in reverse direction?
Yes, the IPVP series can handle highly dynamic reversing operations, which is often done to quickly dump system pressure peaks or to allow generator operation. However, you must ensure that during reversal, the pressure on the primary pressure side does not drop below the suction pressure limit, and the pump must remain fully primed with oil.
