|Pulsafeeder PULSAtron PLUS Series ET chemical metering pumps are positive displacement, diaphragm type pumps with Integrated Feed Control per Water Meter Input. Output volume is adjustable while pumps are in operation from zero to maximum capacity. The PULSAtron PLUS Series ET pump was designed to feed chemical in response to a water meter input. Typical applications include inhibitor feed for an open air-cooling tower. The Series ET provides everything you need in one unique, compact package to create a simple and cost effective metering system. The Series ET counts pulses from a water meter. When the count exceeds a set value (either 1 or 10), the pump starts. The pump will continue to run for an adjustable time period. There are two time ranges - either 2 to 200 seconds or 12 seconds to 20 minutes. The setting is made by selecting a time base value (200 seconds or 20 minutes) and then setting the time base percentage from 1 to 100%. The pump includes both input and output water meter connections at the front panel. The output connection provides an isolated dry contact output of the water meter contact to operate additional pumps or tim ers off the same water meter. There is no need for a separate timer. All timer functions are integrated into the pump eliminating the expense of purchasing an installing another piece of equipment. There are no complicated menu structures. Simply select the desired mode on the front panel and connect the water meter input. There are two selectable time base settings. Choose the time base appropriate for your applications and set the percent value to run the amount of time you desire.|
|Adjustment is by means of readily accessible dial knobs, one for changing stroke length and the other for changing stroke frequency (modes 1 & 2) or changing percent of time (modes 3 through 6). Both knobs are located opposite the liquid handling end. Automatic control via water meter input. Standby-Manual-Count/Time switch.|
|The pump drive is totally enclosed with no exposed moving parts. Electronics are housed in chemical resistant enclosure at the rear of the pump for maximum protection against chemical spillage. Average electrical power consumption is 130 Watts.|
|Materials of Construction|
|Chemical metering pump housing shall be of chemically resistant PBT thermoplastic. All exposed fasteners are stainless steel. Valve seat and seal ring are renewable by replacing the cartridge valve assembly.|
