Johnson Pump Introduces Pump Filter Range

Available in two ranges, four material options and eleven separate sizes offering filtration levels down to 10 microns, the TopFilter provides the pump user with an effective yet simple method of removing debris before it can affect pump performance. Suitable for fitting to either the suction or discharge side of the pump, TopFilters can be supplied by Johnson Pump as an integral part of the pump or as a stand-alone item.

TopFilters are available in single and dual filter models. The single filter, TFOV, contains a single chamber which remains on-line. When the basket within the filter requires cleaning the process line will need to be isolated in order for the filter basket to be removed. The dual filter, TFOW, has two chambers (only one is used at a time) and remains on-line. However, when the filter basket requires cleaning the liquid flow is diverted by handle to the second chamber. The basket can then be removed whilst the process line remains in use. The benefit of this is that there is no downtime.

Both TopFilters offer the end-user the capability to operate the systems on applications up to 50 bar and at temperatures of up to 260ºC and suitable for a range of flanged or screwed connections with sizes ranging between 20mm and 200mm. The application ranges of the TFOV and TFOW can be extended through the availability of a multi-basket filter option, and with restricted pressure ratings this range has the added advantage of a compact design and high filtration levels. A further benefit of this option is that it can be used on connections of 150mm, 200mm and 250mm.
