™ has been specially designed for use in the chemical industry and sewage treatment plants.
The KFI™ pumps by EMM™ are centrifugal, rotary, single-stage, horizontal pumps with a spiral intake channel and integrated base with bearing assembly.
The pumps are comprised of two main units, i.e. the bearing assembly with high capacity bearings applied and the flow system. The immobile parts of these two units are connected with a fastening and centralising ring, while the centrifugal elements are set on a shared shaft. The suction flange is set horizontally to the shaft position, while the discharge flange is set vertically with the pump axis.
The shaft can be sealed in one of the following four ways:
gland with full sealing liquid flow
gland with limited sealing liquid flow
FDS® dynamic sealing system
mechanical sealing
The flow system elements are made with highly alloyed chromium cast iron characterised by a high hardness (approx. 63-65 HRc), with very good abrasion and corrosion resistance. However, due to the main application of KFI™ type pumps in ths chemical industry, the pumps are also produced in versions with austenitic alloys (acid-proof), suitable for pumped slurry.
The design of the pumps enables adjustment of the clearance between the impeller and casing.
The bearing system does not require additional cooling – the bearings are lubricated with oil.
