cause premature bearing and seal failure on any pump. Heat
buildup inside end-suction
generate steam, resulting in dangerous pressures. WDM
recommends that a high temperature switch or pressure relief
valve be installed on the pump body.
• Pumps build up heat and pressure during operation. Allow
sufficient time for pumps to cool before handling or servicing.
• Never pump hazardous materials (flammable, caustic, etc.)
