Air Operated Double Diaphragm Pumps
1 1/2" Metallic
D400-M Heavy Duty
series
YTS powerful 1 1/2” Heavy Duty Diaphragm Pumps were specifically designed for very tough and demanding liquid transfer applications. Heavy Duty mechanically actuated shifting mechanism with non-centering coil spring assisted Air Spools will resist stalling and freezing in all conditions.
Heavy Duty Pumps are able to achieve high flow rates and high discharge heads. They are very reliable and efficient. Pumps possess high slurry and sludge handling ability.
They have fully bolted body, heavy weight construction and wide sturdy steel base. Pumps have double external exhaust ports. Aluminium Air Motor can be PTFE or Nickel coated.
Our pumps are oil and grease lubrication free, with zero exhaust air emissions for safe and environmentally friendly operation. They are easily maintainable with modular replaceable wear parts and outside accessible Air Spools.
