Motor Protector

Upper Bearing

The motor incorporates miniature thermal protectors which are embedded in each phase of the windings to protect the motor from over temperature.

The upper bearing employs an Anti-Creep Bearing.

Cable Entry

Submersible Motor (Explosion Proof)Air filled motor with Class F insulation.Certifications：FM (United States, Canada)Permitted Use：Class 1 (GAS/VAPOUR), Division 1, Groups C & DTemperature Range (T-Code)：T4 (135℃ (275 F゚) )

Shaft SealA tandem design mechanical seal made of highly wear-resistant silicon carbide prevents water from penetraing into the motor chamber.

Leakage DetectorDual probe type leakage detector.

ImpellerThe newly developed impeller was employed by ShinMaywa’s clear technical capabilities as well as taking advantage of the abundant experiences cultivated through years in the pump manufacturing industry.

Hydraulics

Quick, Easy Maintenance

This cable entry employs a core seal that effectively prevents water from wicking down the cable even when the cable end is soaked or the cable sheath is damaged.This feature prevents water from penetrating the motor chamber.

CNX Capacity 158.5~1739 US gpm Total Head 19~113ft

CNXH Capacity 79.2~1447 US gpm Total Head 23~211ft

Applications

The CNX includes our new impeller which has a high efficiency in its operation range.The CNXH achieves a high discharge head by employing our new single vane enclosed impeller. The pass through capability has improved compared to our conventional CN type impeller.
