VOITH IPV / IPVP Series (IPVP4/5/6/7 & IPVA5-64-101) Internal Gear Pumps
Q&A Product Introduction
Q: What are these pumps?
” alt=”” aria-hidden=”true” />
A: They are high-pressure internal gear pumps manufactured by Germany VOITH (Voith Turbo H+L Hydraulic). The IPV/IPVP series are fourth-generation fixed-displacement hydraulic pumps, renowned for ultra-low pulsation, high efficiency, and heavy-duty performance.
Q: What specific models are included?
A:
Main Series (Sizes 4–7)
- IPVP4: IPVP4-13/16/20/25/32-101
- IPVP5: IPVP5-40/50/64-101 (including IPVA5-64-101)
- IPVP6: IPVP6-64/80/100/125-101
- IPVP7: IPVP7-125/160/200/250-101
Key Model Note
- IPVA: Special variant (e.g., IPVA5-64-101) – optimized for specific machine interfaces, same core specs as IPVP5-64-101.
- -101: Standard control/port version; -111 is an alternate variant.
Q: What are the key technical features?
A:
- Ultra-low pulsation: <2% pressure ripple (even <1% in ideal conditions) → smooth machine operation, less vibration.
- High efficiency: Radial & axial gap compensation → 93–98% volumetric efficiency, energy-saving.
- High pressure: Rated 210–330 bar, peak 250–345 bar (varies by model).
- Low noise: <66 dB(A) (DIN 45635) → quiet working environment.
- Heavy-duty: Cast iron body, robust bearings, long service life under continuous load.
- Compact: Optimized involute gearing → small footprint, high power density.
- Multi-configurable: Single, dual, triple pump combinations available.
