Typical Specification Models 4AC, 4AE, 6AC, 6AE, 8AC Bulletin General Furnish and install as shown on the plans, (qty) Weinman Close-Coupled End Suction Pump Series size ( x x ) model centrifugal pump(s). Each shall be capable of pumping GPM when operating against a total pumping head of feet (suction lift/suction pressure) at the temperature, specific gravity and viscosity indicated. The pump shall operate at RPM and shall have percent minimum efficiency at the design point. The pump(s) shall be rated for continuous service and shall be bronze fitted construction suitable for pumping a liquid with the following characteristics: Liquid handled Specific Gravity Temperature Viscosity of liquid at pumping temperature NPSHA Note: Add any additional facts concerning the nature of the liquid or installation which might affect the pump construction, application or operation. Construction The pump shall be coupled directly to a NEMA HP Phase Hertz Voltage RPM Enclosure Motor. The adapter to the casing is to be one piece cast iron construction capable of mounting a Type 21 mechanical seal with carbon/ni-resist faces stainless steel metal parts and Buna elastomers. Casing shall be of cast iron ASTM-A48, Class 30 cast iron with tensile strength of 30,000 psi. Pump unit shall be capable of standing hydrostatic test pressures of 1.5 times maximum working pressure. All assembly points shall be of machine register fit to assure proper alignment. The threaded casing discharge nozzles shall conform to ANSI B16.1 specifications with minimum 125 psi ratings at 180 degrees F (hot water seal rated at 240 degrees F). The casing shall have tapped and plugged drain connections and air vent. The case shall be of the suction cover design for ease of maintenance and service with out disturbing discharge piping, bearing frame or motor mounting. The impeller shall be of the enclosed design constructed of ASTM B584 Bronze (with a renewable impeller wear ring). The motor shaft shall be stainless steel (motor frame sizes 48 and 56) or protected with a (bronze)(stainless steel) sleeve (motor frame sizes 184 to 215) The case shall have a renewable bronze wear ring at the suction. Testing The following (witnessed)(non-witnessed) tests are to be performed in accordance to Hydraulic Institute test standards. Pump performance (A)(B) tolerance level Routine Motor test Hydrostatic - Complete Pump Motor The motor shall be not less than hp RPM, NEMA design B squirrel cage type, (drip proof)(tefc) (EISA)(premium) efficiency motor with (1.15)(1.0) service factor and suitable for operation on (115)(230) volt, 1 phase, (50)(60) Hertz power supply OR (200)(230)(460) (575) volt, 3 phase, 60 hertz power supply. Motor size shall be sufficient to prevent overloading at operating conditions or at the lowest listed head conditions whichever point requires greater horsepower. Following installation, grouting and connection of all piping, pump and motor must be checked for alignment in accordance with standards of the Hydraulic Institute. 2 7/11
