Submersible Stainless Steel Pumps CQ Series

The CQ series is a type of submersible pump made from stainless steel. These pumps are designed with a cutter impeller, which is an efficient mechanism for cutting up solids and debris that may be present in the liquid being pumped.

All parts of the pump that come into contact with the liquid are made from stainless steel, which makes them resistant to corrosion and ensures a longer lifespan. Additionally, these pumps are designed to fit onto guide rails, which makes installation and maintenance easier.

Overall, the CQ series pumps are a reliable and durable choice for applications where solids and debris are present in the liquid being pumped.

CQ series

APPLICATIONS

• Draining wastewater from chemical plant, plastic plant, etc.
• Draining effluent from hospital and laboratory, etc.

FEATURES

All Wetted Parts Made of Stainless Steel
As parts of popular B-series, Tsurumi has come up with BQ-series made of stainless steel casting (SCS13). The shaft, bolts and nuts are made of 304 stainless steel (SUS304) or 316 stainless steel (SUS316). It is suitable for pumping wastewater containing solids and corrosive substances.

Efficient Cutter Mechanism
A sintered tungsten carbide alloy edge is brazed on the stainless steel impeller vane, and it rotates on a saw-tooth suction port of the stainless steel suction cover. This mechanism cuts fibrous matters flowed into the impeller and discharge them.

All Models Available with Guide Rail Fitting
The CQ-series is available with guide rail fittings. Guide rail fitting accessories are made of stainless steel casting (SCS13) or 304 stainless steel (SUS304). Pumps in this series have a ‘TOS’ identifier on top of their model codes.

FLOAT SWITCHES

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.

GUIDE RAIL FITTING SYSTEM

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)
