ESLH

The DESMI ESLH is the end-suction version of the ESL/ESLH family of in-line centrifugal pumps, offered for vertical and horizontal installation. Its suction flange is one size larger than the discharge flange, and the inlet and outlet centrelines are perpendicular to each other and flush with the shaft centreline. The ESL sister version has identical flange dimensions on suction and discharge.

The data sheet gives range values for the whole family: nominal diameter DN 25 to 100, head up to 65 m (220 ft), pressure up to 16 bar (232 psi) and liquid temperature up to 140 degC (284 degF). Flow tops out at 200 m3/h (880 US gpm) at 50 Hz and at 250 m3/h (1100 US gpm) at 60 Hz. The pumps are single-stage, with flanges and motor dimensions built to international standards, and each pump carries a mechanical shaft seal. All rotating parts can be reached without taking the pump out of the piping.

Air-driven or electrically driven priming devices are optional. Motors come as standard or Ex versions, a variable frequency drive can be mounted directly or on a bulkhead or wall, and ATEX approval is available on request. Material choices run from ductile iron through bronze and NiAl-bronze up to super duplex stainless steel. The listed uses are circulation of hot and fresh water, process water, seawater, brine and additive-treated water, as well as refrigeration, HVAC, hydrophore and cooling duties.
