Peristaltic Pump Features and Typical Properties

Peristaltic pump working principle:
LH series peristaltic pump consists mainly of pump house, rotor, roller, idle roller, squeeze tube and driving unit. The squeeze hose is U-shape in pump house, when rotor drives roller to rotate, hose is deformed. After the roller rotate, the deformed hose recover by its elasticity. Thus the negative pressure in this hose is generated, sucking slurries, and discharging through outlet under roller’s push, finally forms pressure conveying of slurries.

Peristaltic pump features:

1. No seals, the peristaltic pump has no seals to avoid problems such as corrosive chemical leaks and ongoing maintenance.

2. No valves, due to the lack of valves, seals and glands, they are inexpensive and require only maintenance hoses or tubes for maintenance. The peristaltic pump also has a gentle pumping action and is ideal for shear sensitive polymers and fragile cell cultures.

3. Self -priming, the recovery of the hose or tube creates a strong self-priming action and allows the pump to move liquid containing trapped air or possibly exhaust gases. The powerful suction provided by the recovery of a re-enforced hose gives hose pumps suction lift capabilities up to 9.5m of water.

4. Only tube to replace, the only replacement part is a hose or hose, which is a relatively low cost product that can be easily replaced in a short time.

5. Dry–running without damage, the peristaltic hose pump does not require continuous pumping of fluids, and the pump can run dry without significant downtime or maintenance costs.

6. Reversible, the peristaltic pump is reversible and can be used to empty the line or clear the blockage.

7. No contact between product and mechanical parts

8. Able to pump products with solid parts inside, hose pumps pump muds containing 80% inorganic solids or 15% organic sludge.

9. Easy maintenance, low-cost, short down time.
10. Gentle pumping action, the peristaltic pump has a gentle, low-shear suction and gentle suction, making it ideal for shear sensitive products, including flocculants and broths.
11. Wear resistance, hose life is independent of the quality of the product. The hose only fails due to fatigue or chemical action.
12. No slip, no internal backflow of the pump, so accurate measurement without slip.
13. Accurate metering, accurate pump metering; their repeatability is ±1% and metering capacity is ±5%.
14. Hygiene, VF flanges are certified to the EHEDG standard for use in the food, beverage and pharmaceutical industries, as well as other health related applications.
