ShinMaywa, the innovation companyWe have continued to make advances by further
developing the CNW/CNWX series of innovative products
with high pass-through capabilities. There has been a
significant increase in sales to the United States.

Features
Toyota City is located in the west of Aichi Prefecture, to the east of
Nagoya City. Toyota City, otherwise known as the "City of the
Automobile", is a company town of Toyota Motor Corporation.
Toyota City is actively tackling the problems common to all humankind,
including helping to create a low-carbon society.
Our CNWX-series high-efficiency, high pass-through submersible pumps
are used in the public sewage system of the city to reduce electricity
consumption and ensure stable operation.
●Facility name: Municipal sewage pump station
●Reduced clogging of foreign matter (Paper diapers, gauze, towels, etc.)
●Lower electricity consumption (run time)

●Change in electricity consumption (at pump station B)
Non-Clog Scroll Submersible Pump
Significantly reduces the clogging, plugging and entangling of fibrous debris that would clog most competing pumps, allowing for less downtime and lower maintenance costs.
Note:Obstacle pass-through may vary with flow rates.
●Pump stations for sewage and wastewater collection systems ●Raw water transfer in pump lift station●Drainage from buildings●Handling of raw water in wastewater treatment plants ●Drainage for industrial wastewater treatment plants●Drainage of wastewater containing debris such as solids and fibrous materials
The CNWX Series are the pumps of choice for the following applications.
Specifications
Applications
ShinMaywa’s revolutionary new single vane non-clog scroll impeller has a helix formed passage at its inlet, and a single vane non-clog passage, which significantly improves solids handling.
Debris is kept away from the low pressure area to improve pass-through

Motor Protector
Guide Rail System
The motor incorporates miniature thermal protectors which are embedded in each phase of the windings to protect the motor from over temperature.
Upper BearingThe upper bearing housing is located above the motor housing.This allows improved upper bearing cooling and maintains bearing life.
Submersible MotorAir filled motor with Class F insulation.
Shaft SealA tandem design mechanical seal made of highly wear-resistant silicon carbide prevents water from penetrating the motor chamber.
Seal Fail Chamber & Leakage DetectorProtects the motor and bearings from damage in the event of mechanical seal failure.
Air Relief ValveThis valve prevents airlock by exhausting any air remaining in the pump housing.
ImpellerOur innovative non-clog scroll impeller has significant design advantages, this is just one of the benefits you would receive from our 50 years of experience in pump manufacturing.
Cable Entry
Innovative Pass-Through Technology
Highly Effective Passing
Quick, Easy MaintenanceThe vertical mounting design allows for easier and more efficient inspection and part replacement.The pump unit can be detached without removing the impeller from the motor.

Core
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.
