TopFilter - Johnson Pump brand
Giving pumps protection from unwanted debris in the pumped media ensures smooth operation and reduces the possibility of damage and subsequent costly downtime. Such protection can now be achieved using Johnson Pump’s TopFilter range of filtration products.
Johnson Pump, an SPX Brand, introduces pump filter range TopFilter |
| TopFilters are available in two ranges, four material options and eleven separate sizes offering filtration levels down to 5 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. |
|
The filters 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. |
