Selecting the Connection Code:
Selecting the proper connection code is probably the most difficult part of choosing a PULSAtron pump. Because of
the flexibility built into this product line to meet a large variety of applications, the connection codes are determined by
alot more factors than just the size of the tubing. Connection code is probably the wrong name for this selection be-
cause you are selecting more than just the tubing size. This code also determines the type of valves used in the pump.
The valve type is determined by factors such as flow rate of the pump, ball type selected and viscosity of the fluid you
will be pumping.
Flow Rate:
The pump you select is rated to pump a certain number of gallons per hour (GPH). When selecting the connection
code, please note the GPH limitations and select a connection that fits within the parameters of the pump model that
you selected.
Ball Type:
If the material selected for the balls used in the check valves is TFE, you will probably need to use a spring-loaded con-
nection. This is due to the fact that the weight of the balls will not allow them to seat properly without the spring. See
the connection chart for a list of spring loaded connection types.
Viscosity:
Viscosity of the fluid you are pumping impacts the connection. The higher viscosity fluids (>3000 cps) require larger
connection types and spring-loaded valves. Medium viscosity fluids (1000 to 3000 cps) can be pumped without the
spring-loaded valves but you must use SS balls with these connections in order for the balls to seat properly in the
valve.
- Pumps ranging from 0.25 gph (0.9 lph) to 0.90 gph (3.4 lph) with the stainless steel ball option (“S” in the 9th
digit of the model number) must select a connection code with a spring.
- Pumps less than or equal to .25 gph (0.9 lph) require a connection code with a spring and must use a ce-
ramic ball in place of stainless steel.
- Stainless steel head assemblies are only available in piping connections.
