Tank Features

 

Design Features—Construction

The tank is made of 10 gauge stainless steel, welded construction, with stainless steel saddles, the heads are made of 3/16” stainless steel. The tank is available in 5 standard sizes, other sizes contact factory for availability.

The pump is constructed of ASTM A48 class 30 cast iron. The mechanical seal is a Type 21 buna- n seal and is rated to 225°F and pressures to 175PSI. Carbon seal face mates with the ceramic seat providing years of trouble free service. The hydraulic design of the impeller maximizes 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. Construction consists of ASTM A48 class 30 cast iron.

The NEMA 56J motor utilizes a stainless steel shaft. The motors heavy duty ball bearings withstand axial and radial thrust loads with no problem. Standard enclosure type is dripproof, alternates are available, consult factory.

The capacity tables are arranged for a variety of loads, discharge pressures and tank sizes. If the boiler is at a higher level or some distance care should be taken in the selection of a pump with sufficient discharge pressure to more than equal A) the maximum boiler pressure, plus B) the difference in elevation reduced to pounds (2.31 feet equals 1 pound) plus C) the friction head sufficiently to permit the selection of a pump having a lower discharge pressure.
