WILO MVI Vertical Multi-Stage Pumps
Multi-Stage Pumps for Commercial, Municipal and Industrial Applications
Presentation Date – Revised Sept 2006
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
30= Nominal Flow Rate (USGPM)
12 = Number of Stages
1 = 304 Stainless Steel (100%)
A3 or O = Flange Type (Size Dependant)
• A3 = ANSI 300 LB 8 Bolt
• 0 = 2 Bolt Oval with NPT Threaded Companion Flange
E or O = Seal Type (S = Std non-cartridge type)
• E = EPDM
• O = Viton
3 or 1 = Three or Single Phase (Coupling Type)
575 = Motor Voltage (all typical voltages available)
21 = Motor NEMA Frame Size
• 21 = 213TC and 215 TC etc…
0 or T = ODP or TEFC Motor
