:: AP Pumps:: Back To Products
The AP Series Advanced Performance Pumps are high-value positive displacement pump for transfer, metering and process applications for all liquids compatible with cast iron.
 
Operating at 50 Hz or 60 Hz motor speeds, these pumps feature the external gear positive displacement pumping principle that provides:
 
Flow proportional to speed
Constant flow regardless of back pressure
Only one shaft seal
High Efficiency, low cost of operation
Ease of maintainance
