Pneumatic air lift pump.
developing 2 in and larger wells.
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 an can be used as
a surge block by moving the pump up and down while pumping. The
simplicity of the pump results in excellent performance when used
in silty well conditions. 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.

A filter regulator is used to optimize air pressure. It should be ordered separately. An optional Quick Exhaust Valve produces higher flow rates in deep applications.
