Inertial Pumps

solinst inertial pumps

The Model 404 Inertial Pumps are a simple and inexpensive option for groundwater sampling, purging and monitoring well development. Pumps are able to handle very silty water. They are ideal for dedication.

The Inertial Pump consist of a length of riser tubing, LDPE or PTFE, with a one-way footvalve connected to the end. Various diameters are available, and stainless steel or Delrin® footvalves are offered. Sizes range from a Mini 1/4" (6 mm) OD Inertial Pump to a 1" (25 mm) OD Delrin footvalve. The sizes allow options for 0.4" - 6" ID wells. When operated by hand, depths of 100 ft. (30 m) can be reached.

The 1/4" (6 mm) OD Mini Inertial Pump (MIP) is made for sampling from the narrow channels of a Solinst Model 403 CMT System.
