These pump housings and mounting brackets are made of cast aluminum or bronze alloy. The rotor is made of stainless steel with a hard chrome plate to improve the wear properties. The stator is manufactured from molded Nitrile. The mechanical seal is a carbon and ceramic mechanical rotating face type for a positive seal.

Walchem cooling tower controllers
The cooling tower control system shall be a capable of measuring system conductivity and temperature.

The conductivity sensors shall be either a contacting style or an electrodeless style. An optional second sensor shall be a choice of pH, ORP, PTSA, free chlorine, total chlorine, chlorine dioxide, ozone, Peracetic acid, or hydrogen peroxide.

Six digital inputs are available for sensors that shall include a flow switch, contacting water meter, paddlewheel flowmeter or other dry contact devices.

Outputs shall include six mechanical relays, and two optional 4-20 mA outputs.

Digital communications shall be via Ethernet. The controller shall be accessible via the Internet for configuring, data logging, and control of relay outputs.

The USB port shall provide the ability to upgrade the software in the controller to the latest version, save all the set points from a controller onto a USB flash disk and import settings into another W600 controller, and download datalog files to a USB flash disk. On screen graphing of one analog signal and one digital signal/relay state shall be available on the touchscreen display.

Ethernet option for remote access via the Internet or LAN

Walchem controllers are designed to control your chemical programs for pools and spas. Accurate readings of the chlorine level in water. Accurate reading of pH and temperature, and optionally, the conductivity PPM levels for the TDS or the salt concentration in the water for the salt systems. Different controllers are available to control the various chemical products; liquid chlorine, pellets or salt system. For the PH control output, you have the choice of the metering pump or CO2 valve.

Some models can be connected to the Internet and send remote alarms, data acquisition files. You can connect online directly on your controller like you were there. V-Touch integrates these centralized controllers on their platform. Everything becomes easier and gives you unparalleled performance.

Our customers have the most accurate and durable installations, we can reduce the cost of chemical programs through precise control of Walchem pH, PPM and conductivity sensors. We can send text messages or emails if the parameters are outside the required limits. We can save the water quality data and obtain specific documents to confirm that your facilities are within the standards set by the various government regulations.

We manufacture several standard systems for our/your customers. These systems are only available through our authorized resellers or exclusive clientele in Quebec and are offered to everyone outside of Quebec (Canada). Our complete systems are targeted for any customers with an offer from a competitor product other than Walchem and Iwaki products.

The possibilities are endless with Stenner peristaltic metering pumps. Select from an array pumps with different operating controls,  flow rate outputs, and operating pressure for applications such as oxidation, disinfection, pH control, or for the accurate injection of additives for a manufacturing or industrial process.

Peristaltic pumps have a great advantage when pumping chemicals like chlorine, peracetic acid and other product that grate air bubbles in the suction line of the pump.

Stenner Pumps – Built with A Strong Work Ethic
• Self-priming against maximum working pressure
• Can inject off-gassing solutions
• No vapor lock or loss of prime
• Tube replacement without tools
• Solid one piece tube construction
• Tube lubrication not required
• Three point roller design assist with anti-siphoning
• Output reproducibility
• Output volume not affected by back pressure
• Foot, prime or de-gassing valve not required
• Some model can pup up to 2500 CPS products
• Some models can detect tube failure
Disinfection
• Disinfection is necessary around the world to provide biologically safe drinking water to prevent waterborne diseases such as cholera, typhoid and dysentery.

• Sodium hypochlorite is a popular form of chlorine that is effective for disinfection and maintains a residual level throughout a commercial or residential plumbing system. Stenner pumps are not affected by off-gassing solutions and can inject chlorine at full strength or diluted with soft water.
