Eradicate hose abrasion from AODD pump pulsations

Edited by the Processingtalk editorial team Oct 6, 2004

A bulk chemicals company used air operated diaphragm pumps: the pulsation caused the delivery hose to scuff on the concrete floor, leading to regular hose failures - a Blacoh Sentry solved the problem

Blacoh Fluid Control recently was contacted by a large manufacturer of bulk chemicals.

They use air operated diaphragm pumps (AODD) to load chemicals into tanker trucks through a 20 foot flexible/ 3" reinforced hose that lies on a concrete floor.

Unfortunately for the company, the pulsation generated by their AODD pumps caused the hose to shake back and forth, scuffing the hose on the concrete floor, and causing "hose abrasion".

Ultimately, these hoses would fail from abrasion due to the scuffing action.

This failure meant considerable downtime, lost product, extensive clean-up, and hose replacement - all of which came with an associated cost.

To solve this problem, Blacoh Fluid Control installed a Sentry 5 gallon Pulsation Dampener at the discharge of each of the 3" AODD pumps.

The dampener absorbed the pulses generated by the pump and the flow from the pump is now smooth and steady.

As a result, the hose no longer shakes and scuffs on the concrete floor.

Since the installation of the Blacoh Pulsation Dampeners, not a single hose has been replaced due to abrasion failure.

The investment in pulsation dampeners has paid for itself several times, in both time and cost savings.

Blacoh Fluid Control also offers a complete line of Sentry Pulsation Dampeners, Surge Suppressors, and Suction Stabilizers to eliminate pulsation and surge in municipal and industrial pumping applications.

The Blacoh Spill-STOP is a patented spill prevention device for air operated diaphragm pumps.
