Description
The Barmesa 2KTM303 is a 3.0 HP, 3-Phase, 230V submersible dewatering pump. Efficiently draining water from flooded areas, construction sites, and underground spaces , these pumps are common in industrial, municipal, and commercial settings to maintain dry and safe environments by preventing water damage and facilitating drainage. They are crucial for de 2" vertical for hose coupling. Cast iron ASTM 48 class 30.
Submersible Dewatering — High Volume, Fast Deployment
Designed for high-volume water removal in construction sites, mines, excavations, and flood control. Semi-open high-chrome alloy impeller passes small solids and debris that would block standard centrifugal impellers.
High-Chrome Alloy Impeller — Abrasion Resistant
High-chrome alloy (HCr) impeller resists abrasive wear from sand, grit, and suspended solids in dirty water dewatering. HCr impellers last significantly longer than standard cast iron in abrasive conditions.
Double Mechanical Seal — Extended Service Life
Double mechanical seal in an oil-filled chamber protects both seal faces from abrasive fluid contamination. SiC-SiC and carbon-SiC seal face combinations provide superior wear resistance in dirty water applications.
IP68 Motor Protection — Continuous Submersible Duty
IP68-rated motor protection provides complete protection against water ingress for continuous submerged operation. Class F insulation handles elevated winding temperatures from demanding duty cycles.
Stainless Steel Shaft — Corrosion Resistance
420 AISI stainless steel shaft resists corrosion at the seal interface — the most common failure point on dewatering pumps operating in aggressive soil drainage and construction site environments.
