Type FY

Qmax=262m3/h – Hmax=34m

APPLICATION

The FY type pumps are designed to handle fluids of higher density and viscosity, such as contaminated water, sewage, juices, lime slurries etc. The typical applications include sugar factories, waste water treatment plants, FDG installations in power plants etc.

DESIGN

Single stage, horizontal, end suction pumps with own bearings and spiral casings. Semi-open impellers are applied in order to reduce the danger of blocking by solid particles. The casing is protected by a liners made of wear resistant alloy. The pumps are of back-pull out design, so they can be disassembled without disconnecting from the pipelines after removing the distant coupling. Gland seals or mechanical seals of different types can be applied depending on the fluid pumped. The bearings are roller type, oil lubricated.

MATERIALS OF CONSTRUCTION

FY pumps are available in different material versions selected individually for each application according to the kind of fluid. In standard version the wet end elements are made of wear resistant chromium cast steel.
