Do You Need a Dampener for Your Diaphragm Displacement Pump?


If you have a commercial operation that relies on a consistent flow of material from one point to another, you may have been experimenting recently with a different type of movement pump. You've decided to try a diaphragm-based displacement pump, as you have been told that they are more efficient and particularly good when it comes to dealing with a graded material. However, you are experiencing some issues with the flow and would like to get to the bottom of this. What steps could you take to fix?

Diaphragm Pump at Work

An air-operated double diaphragm pump is highly efficient when it comes to dealing with viscous or highly abrasive products. These devices use compressed air to operate a diaphragm that shifts back and forth within a pair of chambers. Due to this momentum, liquid is pulled into one chamber and out of the other through a pair of ball valves and with high levels of efficiency.

Causes of Pulsation

It is not unusual, however, for operators to experience some form of pulsation, either in the inlet or discharge piping and this may be due to a number of different factors. For example, you may have a number of different exit points for your material on the downline path and each time that the operator opens the appropriate valve, pulsing may result. This is simply due to an interruption in the natural flow created by the diaphragm action and it can be countered by using a specific form of dampener.

Determining the Requirement

Identify the source of the problem as definitively as you can and be aware, there may be more than one trigger point. If you find that you have several sources, then you will need to introduce a pulsation dampener as close as possible to each location. This device will act as a shock absorber to smooth out any imperfection and, ideally, to get rid of the pulsing effect.

Action Required

Don't underestimate the potential issues associated with pulsation. While it may be annoying, cause inconsistent flow or lead to rattling pipes, it could also lead to a complete failure if left unchecked for a long period of time.

Introducing the Fix

Talk with your equipment supplier, so that you can get pulsation dampeners to help regulate your displacement pump. When installed, you should be able to enjoy an interrupted and highly efficient flow for the foreseeable future.

My Cool Guide to Industrial Supplies

Hey, there! My name is Dan. If you are looking for a cool new guide to industrial supplies, you have come to the right place. The articles I have published on this blog will help you to develop your understanding of different types of industrial supplies. I'm no expert when it comes to this subject but I'm married to a man who works in this sector. Over the years, he has taught me lots of cool things about his work and I thought it only fair to share some of my knowledge here. I hope you enjoy reading this blog.
