EFI-HP™ type

EFI-HP™ series of types is specially designed to be used in filter-press supply. However, due to the considerable lifting height, such pumps are also well-suited to other applications.

The EFI-HP™ pumps by EMM™ are centrifugal, rotary, single-step, horizontal pumps with a spiral intake channel and separate bearing system.

Similarly to the EFI™ pumps, these pumps are comprised of two main units, that is the bearing system where bearings with very high capacity are used and which is fastened to the base, and the flow system, the so-called wet component. The immobile parts of those two systems are connected with a fastening and centralising ring, while the centrifugal elements are set on a shared shaft. The suction flange is situated horizontally in the shaft axis, and the discharge flange can be set in one of eight positions, depending on one’s needs. The pump’s body is protected from the inside with replaceable protective lining.

The shaft can be sealed in the four following ways:

Gland with full sealing liquid flow
Gland with limited sealing liquid flow
FDS^® dynamic sealing system
Mechanical sealing – front

The elements of the flow system are usually made of highly alloyed chromium cast iron (white cast iron) characterised by high hardness (approx. 63-65 HRc), very good abrasion and corrosion resistance, however because of a wide range of possible applications, pumps are manufactured in various material versions, depending on application requirements. For production we mainly use cast iron, carbon steel as well as austenitic alloys – acidproof.

The pumps’ design enables the adjustment of clearance between the rotor’s front and the body.

The bearing system does not require additional cooling, as the bearings are smeared with grease or oil.
