HOSE FAILURE DETECTION &
DAMPENERS

Peristaltic pumps are by nature inherently pulsing in operation. Excessive pressure spikes and pulsations within the pump system can be extremely damaging to the pump hose and the process system.
Appropriate pump selection will ensure pulsations 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 stabilisers can eliminate up to 90% of pressure spikes to protect the pump, pipeline and instrumentation. Other benefits include: reduced vibration, protection against hammer, lower noise levels, increased pump efficiency and prolonged hose life. Specific details and recommendations are dependent upon each application.
Please enquire for further details.

The primary reason for hose failure is from cyclic fatigue (number of hose compressions). 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.
