Rust Removal From Vacuum Pumps – Water Scale, Lime Remover
In order to remove water scale, lime 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
Write down the “before” amperage readings, CFM at vacuum capacity and the vacuum in inches of mercury.
Take the unit out of service.
- Remove the bottom drain plug and allow all water to drain from the pump casing. Replace bottom plug after the unit is drained.
Break seal on water piping and attach a pumping discharge hose.
Remove top plug and attach return hose between there and the recirculating bucket.
Insert “blanks” in flanges of discharge and suction piping.
Add prescribed quantity of Dynamic Descaler into the circulation loop.
In some instances, additional water may be required to maintain circulation.
Tighten vacuum pump and seal packing to minimize leakage.
After 15 minutes of Dynamic Descaler circulation, turn pump rotor 90 degrees by pulling on the drive belts or jacketing the starter switch.
Every 15 minutes thereafter, turn rotor 90 degrees to assure a thorough cleaning of interior part of you pump, including hub and rotor.
Continue the circulation of Dynamic Descaler for at least two hours or until the foaming stops. Lack of foam indicated depleted or clean equipment.
After several hours of circulation time, with intermittent turning of the rotor, the pump should be clean and rotor should turn freely.
- Shut off the circulating pump and add flush water to the recirculation bucket.
