Design Features


Constructed as ASTM A48 class 30 cast iron. The discharge can be mounted in any 90° position. Drain and air ports are also positioned every 90°, 1/4 npt suction and discharge tappings are standard. Back pull out design allows the pump to be serviced without disturbing the piping. The volute was designed to maximize hydraulic efficiency.

Mechanical Seal

Type 21 buna-n seal is rated to 225°F and pressure to 175PSI. Carbon seal face mates with the cermaic seat providing years of trouble free service. Alternate seals available upon request.


The hydraulic design of the impeller maximize pressure and gpm while minimizing horsepower. The enclosed impeller is made of cast bronze.


The precise machining of the adapter allows for easy assembly of the pump. A 1/8 npt hole is provided if a seal flush line is added. Construction consists of ASTM A48 class 30 cast iron.


The NEMA JM frame motor utilizes a high carbon steel shaft. The motor’s heavy duty ball bearings withstand axial and radial thrust loads with no problem. Standard Enclosure type is drip proof but alternates are available.
