- Available as top loading for total fluids, or bottom loading for dissolved phase or higher pumping rates
- Air pressure: 11kPa per meter of depth (0.5psi/foot of depth).
- Air consumption guide: 0.5m3/hr per LPM (1 CFM/GPM)
- Materials of construction: stainless steel, viton, buna-N, nylon, hydlar, ebonite, neodymium iron (magnets), brass and red brass
