Why Choose the VS1-37
- Ultra-high head, compact footprint: 216m discharge head from a vertical inline design that saves up to 50% floor space compared to horizontal pumps
- 37-stage hydraulic design: Stage-by-stage pressure accumulation delivers smooth, low-vibration operation with minimal cavitation risk in high-head, low-flow applications
- All-stainless-steel wet end: 304 construction eliminates rust contamination and ensures long service life in clean hot water and mildly corrosive fluids
- Hot water compatible: Optional high-temperature mechanical seals allow operation with fluid temperatures up to 120°C, ideal for heating and district energy systems
- VFD & PLC compatible: Ready for variable frequency drive and building management system integration for precise temperature and pressure control in heating networks
- Easy maintenance: Cartridge-style mechanical seal allows quick seal replacement without removing the motor or disconnecting piping
- CE certified & 100% tested: Every unit undergoes hydrostatic pressure testing and performance verification before shipment
