Long-established and universally respected, Plenty’s product range consists of high quality strainers that cover a diverse range of different application scenarios.
SINGLE/SIMPLEX STRAINERS 14" & 16"
The Tanker range of basket filters and strainers are for use where flow can be interrupted to allow removal of element for cleaning. They have a very low profile and are well suited to situations where there is limited space to install filters.
DUAL/DUPLEX STRAINERS 1”-8”
A range of small Duplex strainers for use in pipelines operating continuously where a single (Simplex) filter can not be used as the flow would have to be interrupted to clean the element.
LARGE DUPLEX (DUAL) H-TYPE BASKET STRAINER 8" - 36"
The H Type offers a higher flow capacity than the same sized D Type, with sizes up to 36” connections.
SIMPLEX S-TYPE STRAINER 1" - 12" NB
Simplex S-Type fi lters are of simple and robust cast construction with in line connections and can be used in liquids and gases. The Simplex (single) basket type is for general applications where the process flow is intermittent and can be stopped for element cleaning.
DUPLEX D-TYPE STRAINER 1" - 4" NB
Duplex strainers are used for pipelines operating continuously incorporating twin chambers each rated for 100% capacity. An integral flow changeover valve permits basket removal and cleaning without interruption of flow. This range is designed to compliment the Simplex filters but allows the cleaning and replacement of baskets to be carried out without any interruption to the flow through the filter. Fixed stops are provided to indicate which basket is in use. A
projecting flange from the changeover handle guards the cover of the basket in use, making it impossible to remove inadvertently.
DUPLEX D-TYPE STRAINER 10" - 20" NB
The Plenty D-Type, Duplex Basket Filters are designed with two filtration chambers for applications that require a continuous flow whilst the filter is cleaned.
The D-Type employs a rugged and positive method to changeover from the operating to the standby chamber using two disc valves operated by screwed shafts. The shafts are interconnected giving a simultaneous action ensuring that a fi ltration chamber is always in operation. An external indicator is fitted to the shaft to show which chamber is in operation, allowing the basket in the other chamber to be removed and cleaned. The shafts are sleeved and protected from the process liquid.
DUPLEX H-TYPE STRAINER 8" - 36" NB
The Duplex H-Type strainers are designed for larger size applications where interruption of the flow for basket cleaning is not permitted. This range of duplex
strainers employs a simple method for changeover, using two sliding gate valves, operated manually by screwed shafts via an external handwheel. Operating
shafts are interconnected for simultaneous operation, thus eliminating any possibility of completely shutting off the liquid flow. Provided with a valve position
indicator showing which chamber of the filter is on stream. Access to the filter baskets is through quick release covers. The lightweight baskets are quickly and easily removed for cleaning without the need for any tools, lifting gear or specialised knowledge and with minimum down time operation.
SELF CLEANING FILTERS (MANUAL & AUTOMATIC) ¾” - 12"
Self-cleaning fi lters are designed specifi cally to provide efficient filtration for liquids, including those of high viscosity, requiring continuous filtration without interruption to the flow during the cleaning process. There is no operator contact with the process fluid. High quality stainless steel elements are highly effective in removing contaminant particles as small as 25 micron (μm). The filter is available for either manual or fully automatic electric or pneumatic
operation. The range of optional control devices makes it particularly suitable for continuous processes and for service with high contamination levels.
SIMPLEX T-TYPE STRAINER 2" - 12" NB
The Simplex T-Type extends the range of S-Type filters to higher pressures, suitable for both liquid and gas applications and available with bolted or quick release type covers.
COMPACT BACKFLUSHING STRAINERS 3" - 12" NB
Designed specifically for applications on water systems the Compact type of Backfl ush Filters can be installed in process plant making use of river, lake, canal, well and seawater, for nozzle protection, cooling, quenching and various other requirements. The Compact Backflusher is designed to automatically clean when pressure drop rises to 0.35 BARG.
