In order to remove water
scale, lime, mud and rust from the casting, rotor, hub,
cones and associated piping of your equipment, the
following steps should be used.
Instructions for
Dynamic Descaler®
Cleaning
1. Write
down the “before” amperage readings, CFM at vacuum
capacity and the vacuum in inches of
mercury.
2. Take
the unit out of service.
3.
Remove the bottom drain plug and allow all water to
drain from the pump casing. Replace bottom plug after
the unit is drained.
4. Break
seal on water piping and attach a pumping discharge
hose.
5.
Remove top plug and attach return hose between there
and the recirculating bucket.
6.
Insert “blanks” in flanges of discharge and suction
piping.
7. Add
prescribed quantity of Dynamic
Descaler® into the circulation
loop.
8. In
some instances, additional water may be required to
maintain circulation.
9.
Tighten vacuum pump and seal packing to minimize
leakage.
10.
After 15 minutes of Dynamic
Descaler® circulation, turn pump rotor
90 degrees by pulling on the drive belts or jacketing
the starter switch.
11.
Every 15 minutes thereafter, turn rotor 90 degrees to
assure a thorough cleaning of interior part of you
pump, including hub and rotor.
12.
Continue the circulation of Dynamic
Descaler® for at least two hours or
until the foaming stops. Lack of foam indicated
depleted or clean equipment.
13.
After several hours of circulation time, with
intermittent turning of the rotor, the pump should be
clean and rotor should turn freely.
14. Shut
off the circulating pump and add flush water to the
recirculation bucket.
