Features and Benefits
• Impeller: Cast iron, two vane closed design for high efficiency and maximum wear life. Balanced for smooth operation.
• Bronze Wear Ring: Replaceable to renew the running clearances and efficiencies to original conditions. Leakage diminishes considerably.
• Casing: Heavy duty cast iron, volute type for maximum efficiency. 4" ANSI class 125 cast iron flanged. Adaptable to slide rail system mounting.
• Dual Mechanical Seals: Function independently for maximum motor protection. The failure of one seal does not affect the operation of the second. The upper seal uses carbon rotating and ni-resist stationary face materials. The lower seal uses carbon rotating and ceramic stationary face materials as s
• Seal Sensor Probe: The pump has a moisture detection probe located in an oil filled seal chamber. If pumpage should leak past the lower seal it indicates to pump control panel a fault has occurred. Requires an Optional Seal Fail or Moisture Detection Circuit in the control panel.
• Designed for Continuous Operation: Continuous duty submerged condition in water that is 40ºC or below. Maximum runtime with pump unsubmerged for 71/2–15 HP is 1 hour and for 20–30 HP is 15 minutes. Motor is suitable for 10 starts per hour.
• Bearings: Double row angular contact thrust bearing on 250TYS frame and single row deep groove thrust bearing on 210TY frame pumps.
• Impeller Mounting Screw: 300 series stainless steel with antirotational locking patch.
• Castings: All iron castings are ASTM A48 class 30 grey iron. Optional bronze impeller is ASTM B584 C87500 silicon bronze.
