The Martinic QS 400 filter tank is a split polypropylene tank whose upper and lower parts are joined by a heavy-duty steel band with a seal for maximum strength even under operating overpressure.
The side-mounted six-way valve from Praher with 1 1/2 inch internal threads allows switching between all the basic operating modes. The connection of the valve to the tank is made via a union fitting, which guarantees resistance to pump vibrations.
A handling pallet that facilitates transport and placement of the tank at the installation site is also included in the delivery. The filling consists of silica sand with a grain size of 0.4–0.8 mm; the price also includes the internal connection and a pressure gauge.
