2 Casing Standard casing construction of all units is ASTM A8 Class 0 cast iron. All bronze casings are currently available in the D71 and D91 Series only. In all models, the discharge can be rotated to any 90 position and NPT suction and discharge ports are standard. ack pull out design allows the pump to be serviced without disturbing the piping. The volute was designed to maximize hydraulic effi ciency. D1 D61 D71 D91 Series Centrifugal Pumps Mechanical Seal All D1 D61 Series pumps with frame motors use a /8 Type 1 una-n seal which is rated to and pressures to 17PSI. The D71 D91 Series pumps on 1JM through 1JM frames use a 1 1/ Type 1 seal while JM through 6JM frames use a 1 /8 Type 1 una-n seal which is rated to and pressures to 0PSI. The carbon seal face mates with a ceramic seat providing years of trouble-free service. The seal cooling jacket high temperature version of the D1 unit uses a Type 1 Viton seal that is rated to 00 with pressures to 17PSI. Alternate seals are available upon request. Impeller The hydraulic design of the enclosed impellers maximizes pressure and capacity while minimizing horsepower. All standard D Series models feature a cast impeller made of CDA8700 silicon bronze for high temperature resistance. The high temp version of the D1 also features a pressed-on throttle bushing which fi ts snugly into the motor bracket to restrict hot fl uid circulation into the cooled seal cavity. Motor racket Standard construction for motor backets is ASTM A8 Class 0 cast iron, while the D71 and D91 Series are also available in bronze. Precise machining of the D Series motor brackets allows easy assembly of the pumps. A 1/8 NPT hole is provided in the motor bracket for a seal fl ush line if desired. The D1 also comes in a high temp version that has a motor bracket with a cast-in seal cooling jacket which allows fl uids up to 00 to be pumped without damage to the mechanical seal or the motor. The seal chamber is specially machined to allow minimal hot liquid circulation, which keeps the area cool. The water jacket has 1/ NPT ports every 90 for easy water line connections. Motor The NMA JM frame motor found on the D71 and D91 Series utilizes a high carbon steel shaft. The NMA frame motors used on the D1 and D61 Series utilize a 16 stainless steel shaft. The motor s heavy duty ball bearings withstand heavy axial and radial thrust loads. Standard enclosure type is open drip-proof with alternatives available on request.

5 Optional eatures 00 Seal Cooling Jacket xtends maximum working temperature of the D1 up to 00 with an appropriate customer provided external cooling fl uid source connected to the cooling jacket ports. Self-Priming Option The cover casing of the D1 and D61 can be replaced with a self-priming chamber to aid pump priming where lifting fl uids from a sump or lower elevation is necessary. In these applications, the self-priming version lowers maintenance by helping to prevent the pump from running dry and extending the life of the pump seals. Cooling Jacketed D1CD Series vs. Standard D1CD Vertical Configuration The D1 pumps are also available in a vertical fl ange mount confi guration for tank mounted designs and special applications. The standard fl ange is compatible with a Shipco/Dunham- ush/mpco. lange adapter plates are available to fi t other applications.
