Pump is dry Self-Priming up to 20 feet Water Column, so you need not also do initial priming.

Pump is dry Self-Priming up to 20 feet Water Column, so you need not also do initial priming. Pump has no mechanical seals, hence 100% leak proof. Pump can run under Variable Flow, Pressure, Viscosity & Specific Gravity. Pump is completely portable. Pump can run dry without damage. Pump can work under dead head capability ( w/o by-pass valve). Pump has no rotating parts, hence less wear & tear which reduces maintenance. Pump does not require foundation, coupling & complex controls, since the same is run by air. Pump is intrinsically safe, since pneumatically operated. No efficiency loss due to wear. No efficiency loss by changing pressure / flow.
