Product introduction
ES(S),ESD Series single-stage horizontal centrifugal pump completes the liquid transportation by the centrifugal force generated by the impeller of the rotary
pump. Its pump body and motor are composed of main shaft, impeller, pump case and mechanical seal, and connected by coupling.
ES(S),ESD series can work under high temperature and pressure. They are mainly used for heating, cooling tower, air-conditioning system and can be used as booster pump in water supply system. The pull-back structure of axial inlet and radial outlet ensures a more compact pump structure and pipeline.
Design of pump structure
Pull-back design with separated motor and pump body The pump cover bracket acts as a connection between the motor and the pump body, using the 0 -ring as the seal between it and the pump body The flange size meets the requirements of PN 16 in GB/T17241.6 or IS07005-2/DIN2501
Maximum working pressure
Normal type: Pn 12bar
High pressure type: Pn16bar
Performance curves
•The motors used for the measurements are based on
2900rpm or 2950 rom
• Tolerances to ISO 9906
• Measurements have been made with airless water at a
temperature of 20 °C rlll
•The c urves apply to the following kinematic viscosity:
= 1 mm2/s
• Select a best efficiency of the pump which is operating
within the bold curve of the pump performance.
Pump operating conditions
• Pumping liquids which are thin, c lean , non-flammable,
non-combustible or non-explosive liquids, not containing
solid particles or fibers. rlll
• Maximum ambient temperature: +40 °C
• Maximum altitude above sea level: 1000 m
•Totally enclosed, fan-cooled, 2-pole standard motors
• Enclosure class: I P55
• Insulation class: F
• Voltage: 3×220-240/380-415V
1×220-240V
•Available with single-phase motors(0.37kW-2.2kW)
• Normal temperature pump : -15°C to+ 70°C
• Hot temperature pump: -15°C to + 105°C
• Hot temperature pump: -15°C to + 105°C
If the ambient temperature exceeds the 40 °C or the pump is installed at an altitude exceeding 1000 m, the motor output power P2 will decrease. In such cases, it necessary to use a motor with a higher rated output.
