Built-In Features For Precise Dependable Performance

• Motors: Heavy-duty ball bearing close-coupled pump motors with stainless steel shaft. 3450 RPM for greater efficiency and more economical operation.
• Float Switch: Two-pole drip proof case, stainless steel float and float rod, double-break silver-to-silver contacts. Float travel adjustment is easily visible and accessible.
• Automatic Venting: Provides for efficient operation and long life by venting air and flushing seal area.
• Large Tanks: Plenty of capacity for maximum rating of pump. Return inlet is low. Occupies a minimum of floor space.
• Centrifugal Pump: Offers a wide range of pressures and GPM. Unique design features provide for ease of servicing.
• Impeller: Made of brass for long life. Efficient design provides maximum capacity, minimum motor load.
• "SterlSeal" Pump Seal (A): Features the ultimate in ceramic technology for exceptionally long life. Because the seal runs on the bronze impeller hub, the motor shaft is literally outside the pump. Consequently, the shaft is not exposed to corrosion by condensate. Rated for temperatures up to 250ºF.
• Isolation Valve (B): Optional on 4100 Series Condensate Pumps.
