1. WILO MVI Vertical Multi-Stage Pumps Multi-Stage Pumps for Commercial, Municipal and Industrial Applications Presentation Date – Revised Sept 2006

2. Features and Benefits MVI 100 % Stainless Steel Construction Tungsten Carbide Intermediate Sleeve Bearings Teflon seal rings at every stage Teflon resistant to sticking and thermal shock Same Flange Dimension as Competition Tungsten Carbide Mechanical Seals (EPDM or Viton Fitted) Two Flange Types – Model Dependant 2 Bolt Oval Type – Companion Flange Threaded NPT ANSI 300 Lb Round Flange for High Pressure Pumps Uses STANDARD Baldor NEMA Frame Motors Extra thrust bearing in the pump end Ease of motor replacement (no shaft height to worry about) Can use other motor manufacturers Uses standard motor bearings – increases bearing life Built in Priming Plug Built in Air Venting Plug Sleeve O Rings Eliminates Thermal Stress Leaks Excellent Commercial Pump Warranty 24 months from manufacturing, 18 months from installation
