HOSE FAILURE DETECTION & DAMPENERS

---

Peristaltic pumps are by nature inherently pulsing in operation. Excessive pressure spikes and pulsation within the pump system can be extremely damaging to the pump hose and the process system.

Appropriate pump selection will ensure pulsation are kept to an acceptable level. In certain circumstances where other constraints exist, it is possible to fit appropriate pulsation dampening equipment.

Correctly sized pulsation dampeners and inlet stabilizers can eliminate up to 90% of pressure spikes to protect the pump, pipeline and instrumentation. Other benefits include reduce vibration, protection against hammer, lower noise levels, increase pump efficiency and prolong hose life. Specific details and recommendations are depending upon each application. 

The primary reason for hose failure is from cyclic fatigue (number of hose compression). Pump hose failure is inevitable but exactly when hose failure will occur is dependent upon many factors and may not always be at a convenient time when a technician is watching the pump.

Installing a Hose Failure Detector is a simple solution. When a pump hose fails, pumped product is contained within the pump housing mixing with the hose lubricant and raising the liquid level within the pump housing. The Hose Failure Detector will sense this rise in liquid level when connected to a contact relay your system can be set up to switch off the pump or even alert a control room.
