Pump Housing | Cast iron with epoxy paint coating |
Volute | Cast iron with epoxy paint coating |
Impeller | Brass with pressure relief vanes |
Motor | 3450 rpm with automatic high-temperature protection |
Hardware | 300 Series stainless steel |
Bearings | Upper and lower ball |
Shaft Seals | Upper: Type 21, mechanical, spring-loaded, rotating carbon with fluoroelastomer (FKM) bellows, and stationary ceramic with fluoroelastomer (FKM) O-ring. Lower: Rotating silicon carbide with fluoroelastomer (FKM) and stationary silicon carbide with fluoroelastomer (FKM) O-ring. |
Power Cord | Pump: 14 AWG 4-conductor, copper, stranded |
Cooling | The motor housing contains a dielectric oil to cool the motor and lubricate the bearings and seals. The pump is capable of operating with the motor housing partially exposed for extended periods of time, providing sufficient motor cooling and bearing lubrication. However, for the best cooling and motor life, the liquid level being pumped should normally be above the top of the cast iron motor cover. |
Cutters | 440C stainless steel, hardened to Rockwell 60C |
