Can peristaltic pumps pump slurry?
Peristaltic Hose pumps can circulate slurry SGs of 1.6 to 1.8 or up to 80% solid content. The traditional centrifugal pump loses efficiency when the slurry SG reaches 1.3 or 30% solids.
How do you clean a peristaltic pump?
One significant advantage of a peristaltic pump is its ability to clean in place (CIP). When the pump is operating normally in one direction, a cleaning solution can be flushed through the hose in the opposite pumping direction to clean both the pump and upstream piping.
How long does a peristaltic pump last?
Life depends on the hose in speed, outlet pressure, hose material and chemical compatibility, Shen Chen standard peristaltic pump hose life is about 200-300 hours (600rpm, 3 wheel), the lower the speed, longer hose.
What disadvantage do peristaltic pumps have?
Disadvantages of Peristaltic Pumps Due to constant squeezing, the tube wears out on a slow, consistent basis. This can diminish the feed rate if the tube is allowed to deteriorate. The drive motor is under a constant load to keep squeezing pressure on the tube, causing more power usage.
Do peristaltic pumps need to be primed?
Dry running and self-priming Peristaltic pumps do not require pumped fluid to be continually present, and pumps can run dry without costly downtime or repairs. The recovery of the hose or tube creates a powerful self-priming action and allows the pumps to move liquids containing entrapped air or that can offgas.
Can peristaltic pumps run continuously?
Peristaltic pumps may run continuously, or they may be indexed through partial revolutions to deliver smaller amounts of fluid.
Can peristaltic pumps run dry?
Peristaltic pumps do not require pumped fluid to be continually present, and pumps can run dry without costly downtime or repairs. The recovery of the hose or tube creates a powerful self-priming action and allows the pumps to move liquids containing entrapped air or that can offgas.
How do you prime a peristaltic pump?
Peristaltic pumps can run dry to prime. A research laboratory needs to pump dilute sulfuric acid and a copper sulfate solution 24 hours a day for five days in a row. Technicians need to recirculate these two chemicals at 60ºC for a cell lab.
Can you run a peristaltic pump dry?
Dry running and self-priming Peristaltic pumps do not require pumped fluid to be continually present pumps can run dry, without costly downtime or repairs. The recovery of the hose or tube creates a powerful self-priming action and allows the pumps to move liquids containing entrapped air or that can offgas.
Can you dead head a peristaltic pump?
As the peristaltic pump is volumetric and its functioning is positive displacement, an overload of pressure (“dead head” condition) is possible.
What type of pump is a peristaltic?
positive displacement pump
Peristaltic, tube or hose pump is a type of positive displacement pump that transports the liquid through the tube by a series of rollers, that squeeze it against the pump housing, in a similar way that we swallow food.
What happens when a pump runs dry?
Dry running your pump causes friction, and this friction is strong enough to heat up the impeller, causing it to melt. ² Even minor melting is severely detrimental to your pump’s performance, potentially causing it to seize up and stop working at all.
