Description

Floor-standing version of the stand. The stand contains: a frame structure with an instrument panel, a process tank, a centrifugal pump (pumping unit: plastic or stainless steel), a system of pipelines and taps, a tank for working fluid (water), a frequency regulator for controlling the speed of the pump shaft; flow meter for measuring flow with an electronic output to a digital display, absolute pressure sensors with a digital output for measuring pressure values ​​at the outlets and suction of the pump, a system for measuring torque on the pump shaft.
The maximum pump head is not less than 20 m, the maximum flow rate is not less than 60 l/min, the motor power of the pump unit is not more than 0.75 kW. System for measuring power consumption by an electric motor.
Overall dimensions of the stand: length x width x height 1400x750x1700
Power consumption, no more, kW 2
Electrical supply: single-phase 220 V, 50 Hz
Water tank capacity not less than 60 l
