Vertical Pump

We provide variable speed controlled pumping solutions

VFD multistage pump XQ-XR(L) series

MAX. Flow(Q) 130㎥/h
MAX. Head(H) 245m
Operat. Pres. Max. 30 bar
Motor Power 0.75kW ~ 22kW (1~30HP)
Available Power 3PH 380V~440V / 50&60Hz

Description

XQ-XR(L) pumps are built on the basis of XR(L) pumps. Enhanced with the XQ-Drive, the XR(L) pump together with the appropriate sensor is turned into an intelligent, variable speed pumping system. The XQ-Drives are frequency converter integrated into the pump which adjusts the motor speed to provide constant pressure or differential pressure to the flow rate.

Application

Pressure boosting systems, Domestic water supply systems, Cooling Systems, Air-conditioning systems, Small Industrial water supply systems, Horticultural irrigation system

Features

  • 3.5” color display
  • Built-in EMC filter/DC reactor – Reduce noise and harmonic distortion
  • Energy saving (Up to 50%)
  • Maintains constant pressure
  • Simplicity (Eliminates separate control panels)
  • Soft start functionality to minimize mechanical stress on the pumping system

VFD multistage pump NSQ-XR(L) series

MAX. Flow(Q) 130㎥/h
MAX. Head(H) 245m
Motor Power 0.75kW ~ 22kW (1~30HP)
Available Power 3PH 380V~440V / 50&60Hz, 1PH 220V~230V / 50&60Hz

Vertical multistage pump XR(L) series

MAX. Flow(Q) 0.7~130㎥/hr
MAX. Head(H) 245m
Motor Power 0.37kW~45kW (0.5~60HP)
Input Power 3PH 200V~220V/346~380V
Output Power 3PH 220V~240V/380~415V, 3PH 380~415V
Main Frequency 50Hz

Description

XR, XRL pumps are vertical non-self priming multistage centrifugal pump of in-line design, which is driven by a standard electric motor. The motor output shaft directly connects with the pump shaft though a coupling. The pressure-resistant cylinder and flow passage components are fixed between the pump head and the pump casing by means of stay bolts. The pump casing has suction and discharge ports on the same level (in-line).

All pumps are equipped with a cartridge mechanical seal for easy maintenance. XR, XRL pumps are available in various sizes and various numbers of stage to provide the flow and pressure required. The pumps are available with DOOCH variable frequency drive (NQ/XQ/NSQ drive).

Application

Water supply systems, Washing systems, Cooling and air conditioning systems, Water treatment systems, Fire fighting systems, Industrial plants, Boiler feed systems
