RATED DUTY: 1,000 L/min @ 60m
Explosion-proof and flame-proof submersible underground pump.
The KHTX-1030E is a portable freestanding medium pressure pump in the Explosion-proof and Flame-proof Submersible Pump series that is suited to mine water transfer and to medium flow demands. It is a high performance pump both in discharge head capacity and flow rate.
This high pressure pump features a closed impeller and excels in mine water transfer – perfect for medium flow applications. It operates safely in hazardous environments containing explosive gases and vapours with IECEx Certification.
Designed and engineered for high performance with high pressure applications providing reduced down-time and maintenance. This pump features a single impeller with upper and lower suction mouth rings providing increased wear life.
A single oil lubricated mechanical seal is doubly protected by a lower lipseal, totally isolated from the harsh pump flow and abrasion conditions. The mechanical seals are not exposed to the pump operating pressures and conditions providing much longer seal life. The motor is effectively cooled by a separated external water chamber.
Easy care and maintenance design of the wet end makes it possible for very fast maintenance and repairs even underground.
- Power cable specifically designed for submersible applications withstanding temperatures of up to 90ºC.
- Cable entry engineered to reduce likelihood of conductor damage, cables fitted into junction chamber cover via a certified cable gland.
- Lifting Rings: Oversized built-in AISI-304 dual lifting rings for safe handling.
- Minimum bearing life L10 30,000 hours standard for EMQY and EMJY series, bearings packed with lithium grease for high temperature usage.
- Motor housing constructed from rugged cast iron ASTM type 448, Class 35.
- Motor Construction: An air filled, three phase squirrel cage induction motor for submersible or dry pit duty, specially treated stator windings with a treated non-hygroscopic insulation system. Direct online for up to 10HP and Star-Delta winding for 15HP and above are standard.
- Motor Temperature Control: Two automatic-resetting bimetallic thermostats connected in series for limiting motor temperature are embedded in the motor windings.
- Rotor is cast and dynamically balanced.
- Shaft is AISI-420 stainless steel oversized for maximum strength and life.
- Oil chamber lubricates and cools the shaft seals, functions as a buffer preventing water penetration into the motor.
- Leakage Detector: A single-electrode or dual-electrode leakage detectors are installed in the oil chamber for sensing water penetration.
- Shaft Seals: Double mechanical seals prevent water from penetrating into the oil chamber and the motor housing.
- Rated explosion-proof and flame-proof certification for underground mine dewatering.
- Hardware: All external hardware is made of AISI-304 stainless steel.
