SUBMERSIBLE EXPLOSION-PROOF DEWATERING PUMPS [50Hz]_IB113-E

Product catalog summary

Overview: Tsurumi Manufacturing Co., Ltd. offers a range of submersible explosion-proof dewatering pumps designed for use in hazardous environments such as coal mines and oil refineries. These pumps are engineered to handle explosive atmospheres with combustible gases, vapors, or flammable liquids.

Product Series:

KRDX-series: These are heavy-duty slurry pumps equipped with high-chromium cast iron agitators and impellers, recognized by IECEx and ATEX for their wear resistance. They are suitable for draining mud-water and sediment-containing water, with voltage specifications ranging from 380 V to 1000 V.
HSX-series: Single-phase, portable drainage pumps with high-chromium cast iron impellers, designed to prevent air locks.
KTX-series: Three-phase, high-head drainage pumps with a slim design for confined spaces, also featuring high-chromium cast iron impellers.

Key Features:

Explosion-proof structure suitable for hazardous environments.
Equipped with anti-wicking cable entry, motor protector, and dual inside mechanical seals.
High wear resistance due to the use of high-chromium cast iron in critical components.
Designed for continuous duty and reliability in harsh conditions.

Technical Specifications:

KRDX-series: Available in discharge bores of 80-100 mm, motor outputs of 3.7-7.5 kW, and capable of handling solids up to 33 mm.
HSX-series: Features a discharge bore of 50 mm, motor output of 0.4 kW, and solids passage of 7 mm.
KTX-series: Offers discharge bores of 50-100 mm, motor outputs of 1.5-11 kW, and solids passage up to 20 mm.

Certifications: The pumps are certified under various international standards including IECEx, ATEX, and TIIS, ensuring compliance with safety regulations for explosive environments.

Applications: These pumps are ideal for environments requiring explosion-proof equipment, such as underground mines and industrial sites with explosive gases or dust.
