Pulsation in Dual Hose Pump Application

Industry Served: Water Treatment
Problem:

A systems integrator in Pennsylvania was building a new lime slurry storage and transfer silo for an end user in Georgia. The system included two 35 mm peristaltic hose pumps operating in a challenging lime slurry application.

Historically, the integrator did not always include pulsation dampeners on these types of builds, which had led to past issues with inconsistent pump behavior. For this new project, two pulsation dampeners were added to improve reliability. During system testing, however, one of the dampeners failed, creating concern around schedule impact and readiness for shipment.
With the silo build nearing completion and the delivery date approaching, the issue needed to be resolved quickly to avoid delays to the end user.

Solution:

An on site evaluation was conducted to diagnose the issue and support resolution. The system was equipped with two SENTRY pulsation dampeners (175 cu in, PVC/Noryl/Neoprene) paired with the peristaltic pumps.

The failed unit was processed, addressed, and corrected to ensure it met performance expectations prior to shipment. Close coordination with the integrator ensured the replacement unit would be returned promptly and aligned with the project timeline.

Result:

The pulsation dampener issue was successfully resolved, and the corrected unit is scheduled to return to the integrator in time to meet the planned silo shipment date later this month.

With two properly functioning dampeners installed, the lime slurry system is now positioned for:
• Improved pump stability
• Reduced pulsation and mechanical stress
• More reliable operation for a demanding slurry application

The project remains on track for delivery, giving the end user a new system designed for smoother pump performance and long term reliability.
