Model 101 depth to 280 feet at 2.0 gpm; Model 102 flows to 5.0 gpm at depths to 119 feet. Greater surface clearance and closed secondary-containment system are breakthrough innovations improving stuffing-box efficiencies and preserving seals. Mechanical driver and all power are above and outside the wellhead, ensuring no air contacts the fluid being pumped. No fugitive air means less bio-fouling, carbonate crystalization and air locks along discharge line, allowing greater efficiency and longer pump life. Indifferent to pressure, pumps any angle to vertical. Easier, safer, faster servicing at grade -- no pump pulling.
