Self-priming

Pump is self-priming up to 4 m. Intake lines must be air-tight to ensure self-priming. Note: Pump will prime when impeller is dry but suction lift up to 4 m is only obtainable when impeller is lubricated with liquid being pumped or Johnson Impeller Lubricant. For permanent installations where suction lift exceeds 4 m, a foot valve should be used to assure priming on start up. ALWAYS USE JOHNSON IMPELLER LUBRICANT (glycerin) for impeller lubrication. Never use grease or mineral oils.

Continuous duty

For continuous duty 0,6 bar (60 kPa, 8,5 psi) maximum head is permissible. Max ambient temp is +60°C.
