IE B032REPORT ON THE RESULTS OF TREATMENT UNDER CONTRACT No. 1
Pump K-80-60-160: less electricity for the same work
Current under load dropped on all three phases, idle run became lighter, power consumption fell. 16.7–29.7 % — current on all three phases under load, 10.2–12.8 → 8.5–9.0 A; 28.6–39.1 % — current on all three phases at no load, 9.8–12.8 → 7.0–7.8 A (2003).

Key result
| UNIT | SPECIFICATION | WHAT WAS MEASURED |
|---|---|---|
| Pump K-80-60-160 | Centrifugal, overhung type; 4 assemblies of the unit treated | Current on all three phases under load |
| Electric motor AK11212U1 | 7.5 kW · 3000 rpm · cos φ 0.86 | Current on all three phases at no load |
Current under load — the unit's operating mode
| PHASE | BEFORE TREATMENT | AFTER TREATMENT | CHANGE |
|---|---|---|---|
| Phase A | 12.8 A | 9.0 A | ↓ 29.7 % |
| Phase B | 11.6 A | 9.0 A | ↓ 22.4 % |
| Phase C | 10.2 A | 8.5 A | ↓ 16.7 % |
The report records a drop in the unit's current load of 2.7 A after 430 hours of operation.
No-load current — the motor's own losses
| PHASE | BEFORE TREATMENT | AFTER TREATMENT | CHANGE |
|---|---|---|---|
| Phase A | 12.8 A | 7.8 A | ↓ 39.1 % |
| Phase B | 11.4 A | 7.7 A | ↓ 32.5 % |
| Phase C | 9.8 A | 7.0 A | ↓ 28.6 % |
Before the treatment the no-load current was practically the same as the current under load: friction inside the unit consumed almost as much as the pumping itself.

About this result:
Limits of this report: The results refer to the pump unit K-80-60-160 with an AK11212U1 electric motor rated at 7.5 kW; on other units and duty modes the figures may differ. The electricity saving was calculated by formula by the contractor performing the treatment, ChPKP “Rigonda”, and was not verified by measurement.
