Pulsafeeder LVH7 Pulsatron is the pulsatron series HV designed for high viscosity applications for precise and accurate metering control. The series HV offers manual control over stroke length and stroke rate as standard with the option to choose between 4-20mA and external pace inputs for automatic control.
Five distinct models are available, having pressure capabilities to 150 PSIG ( 10 BAR ) @ 12 GPD ( 1.9 lph ) and flow capacities to 240 GPD ( 37.9 lph ) @ 80 PSIG ( 5.6 BAR ), with a turndown ratio of 100:1. Metering performance is reproducible to within ± 2% of maximum capacity.
Features
- Automatic Control, available with 4-20mADC direct or external pacing, with stop function.
- Manual Control by on-line adjustable stroke rate and stroke length.
- Auto-Off-Manual switch.
