The submersible stainless steel pumps SQ2 series are a type of pump that can be submerged in water, and are made from durable stainless steel materials. These pumps feature a Vortex Impeller, which is designed to handle fluids with solids and debris without clogging. This makes them ideal for less-contaminated pumping applications.
In addition to their powerful impeller design, the SQ2 Series pumps also have an efficient motor cooling system that helps to keep the motor from overheating during operation. This helps to extend the lifespan of the pump and keep it running smoothly.
Despite their powerful capabilities, these pumps are also very compact and lightweight. This makes them easy to handle and install in a variety of settings. Overall, the submersible stainless steel pumps SQ2 series are a reliable and efficient choice for pumping applications that require a durable and low-maintenance solution.
• Draining effluent from brewery and pickle factory, etc.
• Supplying freshwater to breeding pond
• Circulating freshwater in aquarium
Ideal for Less-contamination Pumping
Major components in contact with liquid are made of 304/316 stainless steel (SUS304/316) or stainless steel casting (SCS13). In addition to the feature that a non-toxic white oil is used as the lubricant, the pump is suitable for the applications where contamination to the liquid is not desired.
Efficient Motor Cooling
The flow-thru design* always cools the motor and permits the unit to operate at low water levels for extended periods of time. (* Pumped liquid flows around the motor on its way to the top discharge.)
Compact and Lightweight
The design allows the overall dimensions of the pump to be reduced for installation in narrow locations.

Model MC-2 is a heavy-duty type float switch with a shock absorber.
Having equipped with a high grade micro switch, the MC-2 assures trouble-free operation in the liquid containing much suspended solids and floating scum. Either of the two contacts, normally-open or normally-close, can be selected as required.
Model RF-5 is an economy type float which can detect upper/lower limit water levels with single float. The snap on-off action ensures stable operation in clean or waste water containing suspended solids or oil and fat.
The guide rail fitting system connects the pump to and from the piping easily just by lowering and hoisting the pump, allowing easy maintenance and inspection without the need to enter the sump.
When the SFQ, BQ or CQ series is ordered with guide rail fitting, the following accessories will come with the pump as standard equipment (Attach ‘TOS’ to its model code.)
· Lifting Chain 5m (with Shackles)
· Guide Support (with Bolts & Nuts)
· Guide Hook (with Bolts)
· Duckfoot Bend
· Guide Connector (with Bolts)
· JIS 10kg/cm 2 Flange (with Packing, Bolts & Nuts)
