2 Product data Singlestage endsuction pumps Introduction are single stage end suction pumps according to ISO. Our range also includes several model of pumps which have been developed with duty condition which are not covered in ISO. Applications Water Supply. Pressure boosting for high rise buildings, hotels industry etc. Industrial washing & cleaning systems. Fire Protection systems. Cooling & Air Conditioning systems. Boiler feed and condensate transfer system. Irrigation systems for fields including sprinkler & drip irrigation systems. Features & benefits Following are the main features and benefits offered by the pumps. The pumps are non self priming horizontal end suction pumps with axial suction port and radial discharge ports. Standard flanges for suction and discharge ports will be ANSI 1 and ANSI as per ASME B16.1. PN 16 as per DIN standard EN, PN as per DIN standard EN are available on request. Performance and dimensions comply to ISO. These pumps are close coupled pumps with TEFC squirrel cage induction motors with main dimensions complying to NEMA standards M 6. These pumps are available with mechanical shaft seal only. These pumps have the discharge range from to USgpm and head range from 1 to feet. Motor ratings are from 1 to 00 P. The pump impellers are dynamically balanced to grade of ISO 1. These pumps are available with NEMA standard range of motors complying to meet or exceed the efficiency requirements of the US Energy Policy Act of 1 (EPAct) and Natural Resources Canada Standards (NRCan). The efficiency will meet or exceed full efficiency of TEFC motors as per Table 111 of NEMA standards M 6. They can also be supplied with NEMA premium efficiency TEFC motors as per Table 11 of NEMA standards M 6 on request. These pumps feature the back pullout design. As shown in fig. 1 the user can remove the motor, bearing bracket and impeller for servicing without disturbing the volute casing and the suction & delivery pipes. We can also supply pumps with IEC standard motors with aluminum frame from 1 to 1 and motor with cast iron frame from to 1. Fig. 1 Back pullout design

7 Construction Singlestage endsuction pumps Construction features Mounting All pumps up to frame come with pump volute casing with feet and motor without feet (see fig. ). Starting from M frame they come with volute casing with feet and motor with feet (see fig. ). Shaft As shown in the figure an integral single shaft is provided for all pumps from 1M to 6M frame (see fig. 6). Remaining pumps are provided with stub shaft as shown below (see fig. ) which has two drilled holes for set screws in the coupling. Fig.6 Integral shaft pump Fig. Pump design A Fig. Stub shaft pump Impeller The impellers are closed impellers with extra smooth surface finish and machined completely from outside to ensure high efficiency. The direction of rotation of impeller is clock wise when viewed from the motor end. They are dynamically balanced to grade of ISO 1. Fig. Pump design B Volute casing The volute casing of the pumps are designed to be robust in construction to take the undue stresses offered by the pipe work. They have an axial suction port and radial discharge port. Standard flanges are ANSI 1 and ANSI as per ASME B16.1, PN 16 as per EN. PN as per EN are available on request. The volute casing are provided with a priming & drain hole closed by plugs. Fig. Volute casing Motor Adaptor & Back cover Motor adaptors are robust in construction and are provided with an air vent screw in the shaft seal chamber. All impellers can be trimmed to adopt them for the duty point requested by the customer. Fig. Impeller Test pressure All pumps are hydrostatic tested for leakage as per the following test pressure using water containing corrosion inhibitor at room temperature. Pressure rating Operating pressure Test pressure ANSI 1 ANSI PN 16 PN 1 psi psi 16 bar bar 1 psi psi bar. bar Motors The motors are squirrel cage induction motors, totally enclosed fan cooled with main dimension to NEMA standards M 6. The standard motors supplied with the pumps are all as per high efficiency NEMA standards. Premium efficiency motors can be available on request. All motors are available with cast iron construction.

8 Operating conditions Singlestage endsuction pumps Sound/Noise levels As shown in the table below the motor noise levels will not exceed the maximum sound pressure level [db(a)] as per following table. Motor P Maximum sound pressure level [db(a)] Threephase level pole pole 6pole Ambient temperature and altitude The ambient temperature for proper motor operation must not exceed. + F for high efficiency motors + F for premium efficiency motors. In case of ambient temperature exceeding F (or F for premium eff.) or if motor is to be installed more than 0 feet above sea level then a higher output motor should be selected due to low cooling effect. Please refer the chart as shown in fig. for selection of the motors at higher temperature or altitude. P [%] igh efficiency, Lubi t [ C] t [ F] 00 0 m Fig. Motor P depend on temperature/altitude Example A 0 P motors has to be increased in output to P if ambient temperature is F. ft. A 0 P motors has to be increased in output to P if it has to operate at 11 feets above mean sea level. Pump location The Pumps have been designed to operate in non aggressive and non explosive atmosphere. The relative humidity should not exceed %. Pumped liquids pumps are designed for non explosive liquids which are clean, and thin without any solid particles. A viscous liquid affects the pump performance in the following ways. The power consumption of the pump will increase with increase in viscosity. This will require a larger motor for the pump. ead, discharge & pump efficiency will reduce. A liquid with high density will also affect the performance as follows. The power consumption will increase at a ratio corresponding to increase in density. For example a liquid with a specific gravity of 1.0 will this require 0% larger motor to drive the pump. The head discharge and pump efficiency will not change with change in density. Liquid temperature The pump range covers the temperature range from F to + F. The permissible liquid temperature depends on the type of mechanical shaft seal furnished on the pump. Please refer the table showing relationship between mechanical shaft seal & temperature. The maximum liquid temperature is stamped on the nameplate of the pump. Relationship between shaft seals and temperature Seal type Carbon/Ceramic/NBR/ S.S.0 Sic/Sic/Viton/ Carbon/Sic/Viton/ Code Temperature range F to +1 F F to +1 F F to + F Inlet pressure The inlet pressure + shut off pressure (pressure of pump against closed valve) should not exceed the maximum operating pressure of the pump. The minimum inlet pressure must be according to the NPS curve + feet safety margin + correction of vapour pressure. 1
