The Pulsatron Plus Series CW combination pump & controller provides cooling tower conductivity control (sensor & bleed relay) with a water meter input to control pump feedThe PULSAtron Series CW pump was designed to control conductivity and feed inhibitor in an open-air cooling tower. Chemical feed is initiated and controlled by input from a water meter. The Series CW combines everything you need to control conductivity and feed inhibit into one unique, compact package to create a simple and cost effective metering control system.
The Series CW includes a solenoid actuated metering pump, conductivity sensor, bleed relay and a dry contact input for water meter control. At set-up, the operator sets the conductivity set point, differential (or dead-band), the pump stroke frequency and run time. When conductivity reaches the set point, the system activates the bleed relay.
As make-up water passes through the water meter, it generates a series of pulses based on volume of flow. The pump counts the pulses until the total reaches the Count set point. The pump runs at the frequency and run-time specified at set-up and the count is reset.
Features:
- Complete Control System in one unique package. All control functions are integrated into the pump eliminating the expense of purchasing and installing a separate controller.
- Easy to program User Interface. Simply press the universally recognized symbol key identifying the function you wish to adjust and change the value with the up or down arrow key.
- 4-electrode Conductivity Cell. New electrode technology enhances accuracy and stability of the conductivity measurement providing a greater level of control within your application.
- Water Meter Input. The user determines the amount of chemical feed based on the volume of make-up water. Programmable run time, stroke frequency and count set point combine to provide precise control over the amount of chemical used.
- Programmable Limit Timer. If the Pulse Count is set to zero, the timer function becomes a Limit Timer. This allows the user to limit the run time on the pump for each 'feed & bleed' cycle regardless of the input from the water meter. The run time can be set to run up to 24 hours in 1 minute increments.
- Reliable metering performance. Guided check valves with the proven seat and ball designs make PULSAtron the most reliable metering pumps in the world. PULSAtron pumps are known for excellent suction lift characteristics resulting in highly dependable chemical additions.
- Rated 'hot' for Continuous duty. PULSAtron Plus pumps continue to meet their specifications for pressure and capacity during extended use. The solenoid is separately encapsulated in a fin-cooled, thermal-conductivity enclosure that effectively dissipates heat away from the electronics.
- Leak-free, wet end without seals. Our diaphragms are of superior construction - PTFE-faced, bonded to a composite of Hypalon that is reinforced with fabric layers and driven with a metal insert for optimum flexibility and durability.
