Feature Selection Guide
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 vari-
ety 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.
4-20mA Control the pump stroke frequence based on a current input signal from an external device. At 4mA input,
the pump w ill not stroke. At 20mA input, the pump w ill stroke 100%
20-4mA Same as 4-20 except that at 20mA input, the pump w ill not stroke and at 4mA input, the pump strokes at
100%.
External Pace / Allow s the pump stroke to be controlled by an external dry contact closure, such as is provided by a Water
Water Meter Meter. For each closure, the pump w ill stroke one time. Some models provide the ability to multiply or divide
the pulses.
Stop Function A dry contact input that w ill stop the pump on closure and allow the pump to operate w hen open.
Touch Pad Electronic 'touch pad' control w ith internationally recognized symbols.
Digital Display Pump parameters are displayed on an LCD or LED type display.
Signal Relay Provides a 24V DC signal output from the pump based on user specified conditions.
Pow er Relay Provides AC pow er output from the pump based on user specified conditions.
Alarm Display Flashing display or LED indicator that w ill display an alarm condition on the front panel of the pump.
Timed Sequences Ability to pre-program operation for repetitive metering.
Programmable Time
r
Timer that can be programmed w ith up to 8 on/off cycles per day during a 7-day w eek.
Hall Effect Hall Effect Water Meter input.
Conductivity Contro
l
Includes a conductivity controller built into the pump.
Bleed Relay Separate relay used to control a solenoid that w ill "Bleed" a cooling tow er as part of a control system.
Timer Control User defined timer functions that control w hen the pump w ill operate. Used in Cooling Tow er control systems.
Flow Control Optional Flow Sw itch turns pump on w hen flow is active.
