DOSING PUMPS & CONTROL SYSTEMS
mainstay for chemical dosing applications within swimming pool water treatment over the last several decades from dosing of sodium hypochlorite or calcium hypochlorite for disinfection and hydrochloric acid for pH correction and traditionally connected to a pool controller.
Initially dosing pumps employed stroke length adjustment to alter output by reducing the volumetric stroke per pulse and then manual speed in addition to regulate the stroke frequency, ie number of strokes per minute.
A CRIUS AquaSense Swimming Pool Controller is the controller of choice at Crow Wood Leisure in Burnley, Lancashire of the PoolManager® is completely based
on the newest standard web technology and webGUI facilitates complete and entirely transparent remote access from a local network (TCP/IP, Ethernet) or from the internet. Transparent remote access means that the user interface looks exactly the same as the display on the PoolManager®
and is
operated identically. Certain restrictions in remote access are required for security reasons only.
For those that want to treat their pool water exactly the same as in a commercial pool, the PoolManager®
PRO makes this easily
possible. Based on a precise free chlorine measurement, the exact quantity of chlorine is dosed to ensure perfect water quality.
A COMMERCIAL CONTROLLER THAT JUST MAKES SENSE The AquaSense Swimming Pool Controller from Process Instruments measures the pool chlorine levels and pH of the pool and then controls the levels by controlling the chemical dosing. The AquaSense offers bufferless and reagentless operation and is suitable for commercial, municipal and community swimming pools.
The controller is on site in many pools and spas around the world and is the residual chlorine swimming pool controller of choice for many because of its superior chlorine measurement. Spas offer a more difficult
chlorine control problem because of the higher temperatures and the low volume of water, however the controller is still able to offer far superior control in the environment. The sensors used in AquaSense are the same sensors that the company use in their water treatment analysers, meaning the highest quality sensors at the best price. In the modern commercial swimming pool or spa, a swimming pool or spa controller must offer advanced communication and control options, including inverter control. With the AquaSense it is possible to interface to the controller remotely over the internet, enabling data, alarms and setup information to be sent directly to your computer via a 2G/3G modem or via a TCP/IP Local Area Network (LAN). These communication options are essential as in many spas and pools the disinfection control is managed by a service provider who is usually off site. The controllers therefore save time and money as service providers do not have to attend site unless strictly necessary.
Process Instruments usually supplies the AquaSense via pool builders or pool maintenance contractors where they add value by offering a private label option and a bespoke remote access options.
LUTZ-JESCO – A LONG HISTORY IN DOSING PUMPS
Solenoid dosing pumps have been the
pools efficiently and effortlessly. Chemical dosing systems provide an affordable solution to ensuring hassle-free out of water management”

Automating the process is key to helping your customers maintain their
In the last two decades dosing pumps have seen tremendous developments. These include digital displays highlighting flow rate in lph or ml/hr making them easier to use within all chemical metering applications, to automatic degassing heads or valves for sodium hypochlorite, variable speed stepper motors offering quieter, smoother and almost continuous dosing and ideal for use where noise limits prevent the use of nosier solenoid dosing pumps.
Lutz-Jesco dosing pumps have been used within pool water treatment for over 50 years. Key OEMs including JAK Water System where Lutz-Jesco Memdos motor driven mechanically actuated diaphragm dosing pumps have been used for dosing calcium hypochlorite from their Flowtab tablet feeder to Gaffey Technical Services Ltd who have been using the Lutz-Jesco Minidos dosing pumps on their
Hyprolyser Compact Skid electrochlorination systems.
