Frequently Asked Questions about our Putter airless paint sprayer machines

Airless piston pump or Airless diaphragm pump

How to make a choice between Airless piston pump and Airless diaphragm pump?

below are some advantages and disadvantages for your reference.

Advantages Disadvantages
Diaphragm
Pump Spraying
• Good, tight pressure control
across a full range of
pressures
• High free-flow rates,
good for high-volume
transfer of fluids for texture
applications, water, and
so forth
• Lower initial purchase price
Runs continuously
Higher maintenance costs
Difficult to prime
Cavitates easily-air is
introduced into the system
possibly causing erratic
flow or spitting. This usually
is because the pump isn’t
strong enough to move the
coating material.
Poor performance with
higher viscosity fluids as
mentioned above
Must be kept clean (small
moving parts)
Requires constant
maintenance
Hydraulic oil leakage
Frequent diaphragm failure
Piston
Pump Spraying
Pumps higher-viscosity
coatings with ease
Provides higher pressure at
common tip sizes
Better atomization
Allows the use of
longer hoses
Better withstands hard use
Lower maintenance costs
Easy to repair
Primes easier
Runs only on demand
• Higher initial purchase price,
but less expensive to maintain
• Some pressure fluctuations,
noticeable at low
