An infinitely adjustable stroke length of 0-0.6 inches (0-15mm) ensures extremely precise and accurate dosing. The flow rate can be controlled while the unit is stopped or running by a single hand with the manual Vernier scale dial, or remotely using a 4-20mA signal with a rotary actuator upgrade. Multiple drives may be combined with one motor to provide redundancy, or to service several injection points. This feature aids in minimizing cost, footprint, and weight, while maintaining a high degree of accuracy at each individual point regardless of differences in operating pressures. CheckPoint’s Series E and Series F drives can be coupled, and a large selection of motors can be accommodated. These features provide a wide variety of solutions and ensure compliance to any electrical requirements. To meet a wide array of chemical injection applications and to reduce spares inventory through part interchangeability, Series E pumps utilize CheckPoint’s distinguished Series 1250 and 1500 modular chemical heads, which offer a full range of plunger diameters from 1/8” to 1-1/2”.
