Disposal; Diagrams And Drawings - EBARA 1GP Manual De Instrucciones

TROUBLE
Starting too frequent
Pump does not stop
Pump vibrates or makes too much
noise during operation

12. DISPOSAL

When disposing of the 1GP set, comply strictly with the regu-
lations in force in your country, making sure none of the fluid
treated is left inside the pump. Precharge pressure in the
diaphragm tanks must be vented.

PROBABLE CAUSE
- Air precharge in pressure vessel insufficient
- Pressure switch differential too low
- Water leaking from foot valve or piping
Pressure switch outside setting range
- Cavitation due to excessive flow rate
- Cavitation due to suction problems
- Foreign matter between fixed and
rotating parts (fan)
- Bearings worn or damaged

FIG. 4 Opening
- Restore precharge or replace diaphragm
if broken
- Correct setting by increasing the differential
- Eliminate leaks
Correct setting by decreasing the differential (see
chap. 5.7)
- Close delivery isolating valve slightly
- Take the same action as you would when the
pump is delivering low flow rate
- Remove foreign matter
- Contact your nearest dealer
Most of our pumps do not contain particularly pollutant ma-
terials. Specific cases are indicated in the "DEMOLITION"
chapter in PART 2, where applicable.
