Pulsafeeder offers one of the most flexible electronic metering pumps in the world. The product can be configured to meet a large variety of applications and needs. The next few pages will guide you in structuring a complete and correct model number.
The first step in selecting the right model for your application is to select the correct Series. Each Series offers a variety of features that distinguish it from other Series. Within each Series are selections of models that offer different flow/ pressure envelopes to choose from.
The following descriptions will help you understand the different features and then the chart at the bottom of the page will let you select the appropriate models that have the features you need.
Model Selection Guide
Once you have selected the appropriate Series, you must configure the model so that it is built with the features you desire. The Configuration Guide associated with each Series will present the most popular selections. Select one code from each category to build up a complete model string.
To help you better understand the model string, in the following pages, we will explain what each of the digits represent and provide you some additional charts to help you select options not found in the Configuration Guides.
Model Selection:
The first four digits represent the Series and Flow/Pressure Selection.The first four digits represent the Series and Flow/Pressure Selection.
All PULSAtron models begin with this letter. The second letter designates the Series (e.g. Series MP, Series E+, Series A+, etc.). Each series has a different set of features that are available in terms of control and flow/pressure capacity.
The next two digits represent the flow/pressure capacity of the pump.
Digits 3 &4 represent the Flow/Pressure Code.
This code represents the specific flow/pressure rating for the model and can be found in the specification for each Series.
Digits 5 &6 represent the Controls and Electrical selections.
These selections are explained for each model in the Configuration Guide.
Selecting the Pulsatron Wet-End Code &Connection Type:
Digits 7-10 in the string represent the wet-end code. It is the group of four digits set apart by the dash lines.
The four digits in the wet-end code represent the Head Material,Seats &O-Rings, Ball Material and Connection type. Using the above example, the code reads as follows:
- P - Head Material, including fittings. In this example, the P represents GFPPL.
- T - Seat &O-Ring Material. In this example, the T represents TFE.
- C - Types of Balls used in the valves. In this example, the C represents Ceramic.
- 1 - Connection type. In this example, the 1 represents tubing connections for 3/8” OD tubing.
In the individual Series Specification Sheets, we have listed the most popular Wet-End codes. If you don’t find the materials or connection selection to meet your needs, refer to the following selection guides to configure the proper Wet-End Code.
Selecting the Wet-End Code:
The wet-end code represents the materials of construction that will be in contact with the chemical you are pumping. It is critical that the materials selected are compatible. If you do not find the wet-end code to meet your application in the configuration guides, you can use the Wet-End Code Selection Guide to determine the correct Head Material, Seats &O-Rings and Balls. If you do not know what materials are compatible with the chemicals you are pumping, refer to the partial chemical compatibility chart below. We have identified the proper wet-end code for the chemicals in the list. If your chemical is not found in the list, please contact your chemical supplier or clidk here for a complete listing.
- P - Head Material, including fittings. In this example, the P represents GFPPL.
- T - Seat &O-Ring Material. In this example, the T represents TFE.
- C - Types of Balls used in the valves. In this example, the C represents Ceramic.
Tube connection codes are explained in the next section below.
This is an abbreviated version using most common chemicals. Refer to the Chemical Resistance Guide for a more detailed listing.
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 because 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.
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 because 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 (Teflon), you will probably need to use a spring-loaded connection. 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 ceramic ball in place of stainless steel.
- Stainless steel head assemblies are only available in piping connections.
Sensor/Flow Options (Models D, CL, CW & WT Only):
The Series D, CL, CW and WT have optional features that are covered by two additional digits in the Model Selection.
Series D:
These selections are explained for each model in the Configuration Guide.
Suffix Code:
The last three digits of the model string are referred to as the Suffix Code. It is through the suffix code that the pump can be customized with optional features or customer specific features.
This suffix code tells us that you require CE Approval* on the pump you are ordering. This suffix code is five digits and can be used in conjunction with other suffix codes by replacing the XXX after the CZ with another suffix code. For instance, if you require CE Approval and a Five Function Valve (shown below), the suffix code would be CZ500.
*The CE marking (also known as CE mark) is a mandatory conformity mark on many products placed on the single market in the European Economic Area (EEA). The CE marking certifies that a product has met EU consumer safety, health or environmental requirements. CE stands for Conformité Européenne, "European conformity" in French.
Standard Suffix Code Descriptions:
On the following pages are additional features that can be added to your PULSAtron pump through the use of the Suffix Code. Anytime you order a pump with one of these codes, it will be configured with that option.
This suffix code will replace the standard pump tubing with PVDF Tubing:
