SPX Corporation Rotary Pump R4

To properly clean and sanitize the pump for use with food products, it may be necessary to use chemical solutions. Many of the commonly used chemical solutions could cause severe injury to personnel if contacted. The hazard is especially severe for eyes, skin, or inhalation.

Prior to using any rotary pump for the rst time, disassemble and hand clean the pump. Clean all inner and outer surfaces to remove any dirt, grit or lm that may have accumulated during shipment and installation.

1. Do Not use carbon steel wool. Particles may break o and become embedded, causing rust development.

2. Do Not use water high in iron, salt or sulfur. Use distilled water if possible.;

3. Do Not allow cleaners or bactericides to remain on surface for over 15 minutes.

4. Rinse all parts and surfaces exposed to corrosive cleaning solutions completely with cold water.

5. Do Not allow tools or other metal items to lie on wet stainless steel.

6. Only use recommended cleaners. Alkaline dairy cleaners or bactericides should contain a wetting agent and polyphosphate to suit water hardness.
