Frequently Asked Questions - Components
Dynex pumps can pump a lot of different fluids under a wide range of conditions. Water unfortunately does not provide enough lubrication between the bearings and pistons to operate successfully. Our water based products (PF1300, PF4300) are designed to operate on fluids that are up to 95% water.If you have an application that uses a fluid with a high concentration of water, please contact Dynex to discuss the application.
Our ports conform to SAE specification J1926/1 / ISO 11926-1. Fittings are supplier specific. Please consult fitting manufacturer for pressure limits.
A brand of coned and threaded connection used for sealing at higher pressures. These are available in three pressure ranges. Up to 15,000 psi (low pressure), 20,000 psi (medium pressure) and 60,000 psi (high pressure).
Recommended inlet condition depends on specific pump model. All checkball pumps perform best with at least a positive head.
That depends on the pump model and fluid viscosity. Refer to literature for the specific minimum inlet pressure for specific pump models or contact the Dynex Sales Department.
A Duty Cycle is defined as the relationship between the active (operating) time and the inactive (resting time) of an equipment or machine. Intermittent duty depends on the operating conditions. We recommend you submit a Pump Application Worksheet or consult the Dynex Sales Department for the best recommendation as to which model pump to select for your application.
Yes, provided the air bleed/drain for the particular pump model is oriented up and is accessible.
Minimum / Maximum speeds depend on the specific pump model and fluid type. Refer to Dynex literature for the maximum speed and consult the Dynex Sales Department for the minimum speed for specific model pumps.
