SOFT START TECHNOLOGY
A BREAK THROUGH IN SUBMERSIBLE PUMPS PROTECTION & CONTROL
Model 1PH-SS with all the features plus SOFT START, now available
We have created new technology. The motor receives power gradually, from the start of movement to its maximum speed in three seconds, bringing the pump out of the stand still condition; the high peak starting current is reduced by more than 75% and mechanical stress greatly minimized.
Electricity commissions around the world are restricting the start of motors to a limited peak of current. Typically when power is switched ON a high peak of current occurs. This causes disturbances in the mains electricity supply, therefore greater energy is necessary to avoid voltage drops; this at a greater cost.
Pumptron complies with the regulations, but it wasn't the only reason for this development; it was because of the many problems associated with the starting of submersible pumps. Lets analyse: When a pump is standing still submersed in the water and suddenly power arrives, in full; before movement begins, the motor generates a high peak of current as the energy is not transformed immediately into motion. Then movement begins and in a fraction of a second it reaches maximum speed. The pump's impellers suffer the shock of an instantaneous physical mechanical force. Some twisting effect in the axis causes stress in the bearings and all moving parts. The initial pressure in the water creates physical stress in the pipe. In order to avoid this from happening, companies advise that the water flow be adjusted restrictedly according to the bore water production, so the pump runs continuously. This significantly increases power consumption; if the amount of water produced by a bore in a day can be pumped out at full thrust in four hours, running it continuously results in extra twenty hours of unnecessary power consumption, therefore increasing the power bill accordingly.
Recommended for Single Phase pumps up to 30 Amps 120 and 240 Volts
Highly recommended for pressure systems where the pump starts and stops repeatedly.
