Chem-Tech Series XP chemical metering pumps are preferred by many water treatment plant operators because their unique tubing-driven pump heads offer natural degassing and are completely self-priming. This makes them ideal for feeding gaseous chemicals such as sodium hypochlorite. The standard low pressure pump tube provides an extended service life. High pressure versions of these tube pumps are also available.
These adjustable dosing rate models feature a single control dial that adjusts the pump on/off cycle time. Rates are infinitely adjustable from 5% to 100%. The cycle time is 2 seconds and the adjustment dial provides the setting percentage as the amount of time that the pump is on in each 2 second cycle. For example, a dial setting of 5% provides a 0.10-second on-time and corresponding 1.90-second off-time. Conversely a setting of 95% provides a 1.90-second on-time and corresponding 0.10-second off-time.
Pump comes complete with a suction strainer, an injection check valve assembly and standard (low pressure) norprene tubing with 1/4" connectors.
