As with all CS series pumps, the CSD features an open impeller
and a clamp casing, seal design and back pull out IEC standard motors, which allows for quick disassembly and inspection.
The pumps feature open impellers
with two times the wear area of a closed design, which optimizes the performance of the pump's open impeller
and allows renewable performance.
The open impeller
examined in this study was a radial flow six-blade RT with a diameter of D = 6.53 x [10.sup.-2] m.
Traditional trash pump impellers are based on an open impeller
design that includes an adjustable back wear plate.
Models are available with a choice of low flow vane impeller and fully open impeller
, thereby accommodating both low flow conditions and liquids containing solids and abrasives that seriously reduce the performance of enclosed impellers."
Available from Pump Engineering, CSF pumps are manufactured in investment cast AISI 316L stainless steel for all wetted parts and feature a six vane open impeller
that facilitates the handling of liquids containing particles or small solids.
The MFV-160 pump has a four-vane, open impeller
, giving it a maximum flow rate of 1425 gpm and maximum total head of 155 ft.
The impeller consists of blades attached to a revolving shah, which may be fastened between two round plates (a "closed impeller") or may not be so enclosed, but with enough tolerance to clear the sides of the casing ("open impeller
Designed for CIP (Clean in place), and highly reliable, the F&B-Hygia is made from AISI316 stainless steel with an open impeller
and mechanical seal positioned in the flow of the product for optimum clean ability,
