The Arch Pump is a pneumatic air displacement pump used primarily for well development in 2 in. and larger wells. The pump will produce flow rates up to 2.5 gpm and The simplicity of the pump results in excellent performance without pump damage when used in silty well conditions. Additionally, the Arch pump can be used as a surge block by moving the pump up and down while pumping to enhance development energy.
The pump design provides easy component access, consisting of a stainless steel pump body and head, a Buna-N bottom check valve and a stainless steel fluid discharge line with a check valve. The pump head has two 3/8 in. barb fittings for the air supply and fluid discharge.
The Arch Pump Controller is required to set the intake and discharge times that regulate the pumping rate. It is placed at the ground surface between the air compressor and the air tubing leading to the pump. The controller is compact and manufactured of stainless steel for rugged field use. An optional Quick Exhaust Valve produces higher flow rates in deep applications.
The controller must be supplied with clean dry air at a minimum pressure of 40 psi with approximately 1.5 CFM free air per gallon of water pumped. For best results a minimum of 4.0 CFM from the compressor is recommended. Maximum pressure of 100 psi. A filtered regulator is used to optimize air pressure. Order separately.
