Large Duplex D-Type Strainers

---

The Plenty D-Type Duplex Basket Filters are designed for applications with high flow capacities.

The unit consists of two filtration chambers for applications that require a continuous flow

while 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 filtration 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.

Large D-Type Duplex are available in Cast Iron and Cast Steel
