Design and Construction Specifications

Casting: A radially split first stage volute with integral suction cover and 250 psi ANSI flat faced flanged suction connection. Foot mounting of the casting allows removal of the rotating assembly without disturbing the suction piping.

Impellers: The fully enclosed end suction impellers are both one piece castings, fully machined, trimmed to the exact diameter required for the application and factory balanced. The impellers are mounted back-to-back, keyed to the shaft, and are secured by a locknut and washer.

Stuffing Box Cover: A heavy one piece casting with an integral second stage volute and 250/800 psi ANSI flat faced flanged discharge connection. The deep stuffing box will accept a range of Packing or mechanical seals. The discharge connection is in the top centerline configuration.

InterStage Diaphragm: A solid casting precisely machined and fitted between the first and second stages. The diaphragm to casing and diaphragm to stuffing box seals are fully contained "O" Rings, except on the Model 1-1/2TC, which has Gasketed interfaces.

Gland: A split gland for packing, or solid for a mechanical seal, can be provided in a quench design if required.

Shaft: The precision machined high quality alloy shaft is normally fitted with a renewable sleeve, and is sized to minimize deflection to ensure smooth operation and maximum packing or seal life.

Shaft Sleeve: An easily removable stainless steel sleeve is standard. The sleeve is sealed against the shaft by "O" Rings and is secured by double locking screws. Hardened Sleeves available on request.

Bearing: Standard grease lubricated ball bearings are rated for 2 years minimum service at full load and speed. Oil lubrication, with or without cooling, is available.

Bearing Housing: A rigid casting precision machined to ensure accurate bore and rotating element alignment.

Adaptor: A rigid casting with an integral gland drip reservoir, precision machined to connect the bearing housing to the liquid end of the pump.

Hydraulic Balance: Back-to-back impellers ensure full axial balance while 180 degree opposed cutwaters provide effective radial balance.

Temperature: Standard packing or mechanical seal, and grease lubricated bearings are satisfactory to 250 degrees Fahrenheit on water, depending on additives and operating conditions. Optional seals or packing, quench glands and oil lubrication with or without cooling, are available for higher temperatures.

Interchangeability: All pumps utilize a common bearing housing and have interchangeable bearings, Packing, seals, glands, and hardware, resulting in efficient parts inventory at the factory for the customer.

Tests: All pumps are hydrostatically tested to 100 psi above the maximum design pressure.

Optional Equipment

Base: A rigid channel or fabricated base can be provided to our standard for electric motor drives. Special bases can be provided and can incorporate grout holes, drip rims, and other features.

Guard: A coupling guard to our standard can be mounted on the baseplate. Special guards can be accommodated. Flexible Coupling: For normal duty, our current standard is provided when a coupling is ordered. However, couplings of almost any style or manufacture can be accommodated.

Motors: An electric motor or other driver can be provided.

Special Features

Wear Rings: Casings and impellers can be provided with wear rings. However, there are not recommended except for special applications or circumstances.
