Bronze Gear pump For Hydraulic Motor

Gear pumps are positive displacement pumps. Each shaft revolution displaces a definite amount of l9iquid relatively unaffected by the back pressure in the discharge line. Shaft speed and flow are directly proportional. Recommended pressure limits are 100 psi for water and non-lubricants, 150 psi for oil and lubricants. Maximum shaft speed is 1750 rpm.

A relief valve is necessary in the system if the discharge line contains any throttling devices, such as a shut-off valve, a spray nozzle or other restrictive device. For pressure or flow control device purpose a separate relief valve in the pressure line must be used.

De-icing pump, often hydraulically driven by a Danfoss or Bosch hydraulic motor on salt or sand trucks. Sprays magnesium chloride or other solutions. Uses such as snow melt liquid deicer deicing: Potassium Acetate, Sodium Formate, 32% Calcium Chloride, FAA Compliant Ice Melters, Peladowï½®, LS25, LS-25 CI, and a variety of Environmentally Friendly products SnowMelt. Prewetting / anti-icing, salt pre-wetting systems, salt brine, calcium & Mag chloride, potassium acetate.
