Linearizers
They use a flexible membrane to separate the liquid chamber to be treated from the compressed air supply and are mounted as close as possible to the pump to maximize its effects.
They exist in a preloaded passive version or in the active version, both automatic and adjustable: their use prevents excessive wear of the whole system (pumps, valves, flow meters, process instrumentation, …) ensuring a maximum efficiency control.
Sand Piper Tranquilizer
They can be used with any pneumatic double diaphragm pump, allowing to maintain acceptable linearity of flow as well as to contain water hammers generated by pressure peaks. They must be positioned in line and as close as possible to the pump outlet. They work by means of a derivation on the compressed air line, at the same pressure of the pump. They are available in various versions, such as aluminum, AISI and cast iron and plastics, such as Polypropylene and PVDF, and 1 ” to 3” models.
