Benefits to Installing a Pulsation Dampener

Benefits to Installing a Pulsation Dampener

Positive Displacement (diaphragm) pumps create pressure pulsations (spikes) and hydraulic shock due to their stroking action characteristics.  These pulsations potentially can harm, damage or shorten the life of system components.  A properly set-up and sized pulsation dampener can remove up to 99% hydraulic shock, noise and vibration. Pulsation dampeners also create continuous flow enhancing all-around performance in industrial and chemical dosing applications.

How do they work?

The pulsation dampener creates a low pressure area in the system large enough to absorb pressure spikes.  The pulsation dampeners membrane made of chemically resistant materials, e.g., Teflon®, Viton®, etc. compressed air behind the membrane causes it to flex when exposed

to a pressure spike, dampening (cushioning) the pressure spike. Properly pressurizing the pulsation dampener will maximize its effectiveness. The initial “charge” should be 80% of the system’s operating pressure. Air is then added or released via a Schrader valve until system vibration is eliminated.

Troubleshooting PULSAtron Pumps

Troubleshooting PULSAtron Pumps

PULSAtron pumps are electronic metering pumps, which simply means that an electronic circuit controls the charge and discharge of a solenoid driven diaphragm. A DC current energizes the solenoid pushing the diaphragm forward within the pump head for the discharge of fluid. When the current is removed, the solenoid de-energizes, allowing the diaphragm to retract (spring assisted), pulling more fluid into the pump head. The two main components to troubleshoot are therefore the solenoid and the circuit board.

The solenoid is simply a large winding of electrical conductor with a specific resistance. If this resistance is out of tolerance, then an improper current would result, impeding the proper operation of the pump. PULSAtron pumps have a distinct operating clack as the solenoid goes through its’ charge/discharge cycle and when absent, we know its’ time to troubleshoot. By removing the control panel (located in the rear of the pump), we can access the two wires connected to the circuit board to the solenoid. Power should be disconnected from the pump before removing the control panel! Remove these wires from the board by pulling on the connectors at the board (no tools required). Once removed, measure the resistance of the solenoid wires and if the reading is out of tolerance, the solenoid should be replaced.

If problems do occur and the solenoid is within specification, look to the circuit board. Since it is not practical to troubleshoot individual components on the circuit board, we discuss ways to identify circuit board problems in general, which are then addressed through replacement of the circuit board itself.
For Series E Plus models where a 4-20 mA input signal is utilized to control the pump flow rate and the pump is not responding to the 4-20 mA input signal, first make certain that the proper polarity connections have been made to the pump. The cable provided with the pump has a molded end which plugs into the 4-20 mA terminal on the pump (this terminal is marked on the pump). At the other end are two insulated conductors, white for positive and black for negative. If these conductors are reversed the pump will run at maximum stroking rate with no response to changes in the 4-20 mA input signal. If conductors are connected correctly and the unit fails to respond to changes in the 4-20 mA signal, the circuit board should be replaced.

For unit where External Pacing is an option, performance can be verified by shorting the two conductors at the end of the signal cable or by shorting the pins at the control panel (marked EXT). Each time the conductors or pins are shorted, the pump should stroke once. The circuit board on PULSAtron units has been designed to achieve the longest service life of any comparable product in the market. However, you can take simple measures to extend the service life even more. Make sure that all wiring is to code and try to avoid sharing electrical lines with high horsepower motors since the high energy level of induction motors can create voltage spikes which may result in circuit board damage. This can be prevented with the use of surge protectors or by isolating the pumps power source. Lastly, always minimize the stroke rate by operating the pump at full stroke length.

Multiple Pump Models Address Different Chemicals and Flow Ranges for a Wide Variety of Applications in the Water Treatment and Chemical Processing Industries

Rochester, NY – (PRWEB) – Pulsafeeder, a global leader in fluid handling technology since 1942, today announced the Eclipse Series of Metallic Gear Pumps. With 12 different metallic and non-metallic pump models, the Eclipse family of gear pumps addresses a wide variety of chemicals, connection sizes and flow ranges for water treatment and chemical processing applications.

The Eclipse family of gear pumps features a patented front pull-out design that makes routine maintenance faster and easier, with a minimum number of tools required. The Eclipse series features the fewest number of parts compared to any other external gear pump on the market. Pulsafeeder’s KOP (Keep-on-Pumping) kits provide all of the spare parts required to further simplify maintenance and minimize downtime.

The new versions of Eclipse offer enhanced performance, and new flange options. Eclipse now offers two different types of metallic gearing – Alloy C and 316LSS – for addressing higher temperatures (up to 450-F/232-C) and wider viscosity ranges for process chemicals.

Each member of the Eclipse series is magnetically driven, with no seals to wear or replace, providing the safe and leak-free handling of highly corrosive fluids in a wide range of temperatures.

“The true value and advantage of the Eclipse line is realized when customers consider the performance, the reliability and the simplicity of maintenance required over the life of the pump,” said Axel Bokiba, Vice President of Product Management for Pulsafeeder. “With the Eclipse family, we’re providing customers in the water treatment and chemical processing industries with a flexible solution to address any of the chemicals they need for their processes, and we’re doing this at a price point and total overall value that no other pump manufacturer can match.”

The complete line of Eclipse Gear Pumps includes the 02, 05, 12, 25, 75 and 125 models in metallic and non-metallic configurations. For more information on Eclipse Pumps, please visit: http://www.pulsa.com/eclipse.
