Application
USR/USRF is used for conveying cooling liquid,
lubricating liquid and condensation water of machine tools,
industrial cleaning equipment or other cases that application
of immerged pump is suitable, and is applicable to various
temperature, flow and pressure ranges. USRF is applicable
to low-corrosive liquid.
Concretely, it is applicable to electric spark, lathe, grinding
machine, processing center, cooling devices, industrial
cleaning equipment, filtering system etc.

Operation conditions
Thin, clean non-explosive liquid without solid grains and
fibres; can be used for conveying of water, cooling water
solution and cutting lubricating liquid.
Liquid temperature:
O Normal temperature type : -15 ~ +70℃
O Warm water type: +70 ~ 120℃

Pump
USR/USRF is non-self priming multi-stage centrifugal
pump installed with standard motor. The motor shaft
is directly connected with the pump shaft through coupling.
According to the requirement, the pump can be equipped
with intelligent protector, which effectively protects pump
from dry rotation, phase lack, overload etc. In order to meet
the requirement of installation depth of the water tank or vessel,
it is possible to install cavity body for changing length
of the pump. Length for different number of stages is shown
in the dimensions & weight table and the table of products
supplying scope.

Motor
The motor is fully-sealed, air-cooling standard motor
2 poles
Protection class: IP55
Insulation class: F
Standard voltage, 50Hz: 1x220 - 230/240V
3x200/346V
3x220 - 240/380 - 415V
3x220 - 255/380 - 440V
Standard voltage, 60 Hz: 3x220 - 230/346 - 440V
3x 220 - 255/380 - 440V
3x220 - 277/380 - 480V
Motors for other voltages can be supplied according to
the requirement.Single phase motors with 0.37 ~ 2.2kW are available.
Max ambient temperature
When the pump operates under ambient temperature
higher than 40 or under altitude higher than 1000m,
because of low air density and poor cooling effects, the
motor output power P2 will be decreased to certain extent.
If the pump is operated under the above-said conditions,
it should be equipped with motor of higher power.
