Piston Pump Motor Techologies

AFX™ reliability features:

 
1

Progressive Exhaust™ Parabolic valve geometry and cascading expansion chambers practically eliminate variability in pump performance caused by changing environmental conditions and icing.

 
2

True Link Valve™ Our pulse profile is virtually undetectable. Highly polished ceramic valve plates and PTFE-filled acetal valve components are directly linked to the drive piston, creating an industry-leading changeover time of less than one-tenth of a second. There are no springs to fail or consume energy. Patent pending.

 
3

Fiber-wound, conductive composite cylinder has superior seal wear created by the epoxy surface; metal cylinders can seize with piston if seal failure occurs.

 
4

Lubrication-free operation saves you the cost of lubricating your pump.

 
5

6'' stroke results in improved performance for your process with high displacement per stroke, improved pulse profile, and reliability due to fewer switch-overs per cycle.

AFX™ designed simplicity features:

 
6

Universal valve block reduces downtime since it’s easily serviced and interchangeable between all motor sizes.

 
7

Universal lower end pump connection permits interchangeability between various sized air motors and pump ratios — you may upgrade the motor
without buying a new pump.

 
8

Compact design makes it easier to incorporate our pumps into OEM equipment.

 
9

Actuation control ports provide access for pneumatic logic signal controls. Patent pending.

AFX™ safety features:

 
10

Groundability provides safe operation where static charge build-up and sparking is a concern. Our groundable pumps are ATEX-compliant.

 
11

Optional integrated ball valve regulator enhances safety by enabling air pressure to be set using a regulator, to be checked visually by reading the gauge, and to be dumped manually; also completely eliminates need for installation and expense of extra plumbing, regulators, or valves. Patent pending.

Hydraulic motors also available for select models.
