Peristaltic Hose Pumps: Frequently Asked Questions

What is a Peristaltic Hose Pump?

A Peristaltic Hose Pump works by either two shoes (high pressure applications) or rollers (low pressure applications) rotating on a wheel inside of the pump and compressing an internal hose, which then forces through a known quantity of fluid. The hose inside of a Peristaltic Hose Pump is designed to return to its original shape after the shoes or rollers have passed over, so the quantity and flow of fluid is consistently maintained.

How a Peristaltic Pump works

What’s makes Tapflo’s hoses different?

Tapflo manufacture hoses by pressing layers of high quality rubber together. We only use thehighest quality material, and the way they are layered and compressed means they are one of the strongest hoses on the market.

Multilayered Hose

Multilayered hose for a Peristaltic Pump

Only a handful of manufacturers worldwide are able to make the hose according to our specification. Our hose lasts approximately 30% longer than other hoses available on the market, due to 3 technical reasons:

1. Higher quality of rubber

2. Better shimming strategy

3. Better hose selection strategy

Hoses can be supplied in the below materials to suit a wide variety of applications:

  1. Natural Rubber

  2. NBR

  3. Natural Rubber FDA Approved

  4. EPDM

  5. FKM – Viton

  6. CSM Hypalon Rubber

The price of the hose usually works out to around 8 – 10% of the cost of the pump.

What are the benefits of a Peristaltic Hose Pump?

There are tonnes of benefits to the Peristaltic Hose Pump technology - so many in fact that there’s a few too many to list them all! See some of our favourites below:

  1. They are fully self-priming up to 9.8 meters – not many other pumps on the market can produce that kind of suction!

  2. Damage free when dry running

  3. Outlet pressures of up to 15 Bar

  4. Suitable for aggressive and viscous fluids

  5. Very easy maintenance

  6. Safety – the only part of the pump that comes into contact with the fluid is the hose!

  7. Reversible flow

  8. Heavy duty bearings, greased for life

What flow rates can I get out of a Peristaltic Hose Pump?

One of the great things about Peristaltic Hose Pumps is how versatile they are when it comes to flow rates. The pumps in our range start as low as 10 LPH and can go all the way up to 3000 LPM!

What applications can you use with a Peristaltic Hose Pump?

Our Peristaltic Hose Pumps are suited for both low & high pressure transfer, metering and dosing applications of low or high viscous, pasty, pure, neutral, aggressive or abrasive liquids, those containing gases or which tend to froth, or those containing solids in the following industries:

  1. Food & Beverage: tomato sauce, mash potatoes, gelatine, beer yeast, fish paste, olive oil, wine, egg white & yolk, edible fat, semolina, natural flavouring, cream, milk & yoghurts.

  2. Bakeries: water & salt mixtures, natural flavourings, fats, fruit cake dough/mixture (i.e. fruit cake has nuts and fruit pieces that need to stay whole).

  3. Paint: water based paint, acrylics, pigments, ink, wall coating.

  4. Meat and Fish processing

  5. Pharmaceutical & Cosmetics: chemical dosing, liquid protein, vaccines, serum, plasma, syrups, shampoos.

  6. Waste Water & Water Treatment: lime cream, ferric chloride, sodium bisulphate, fluoride, polymers, aqueous ammonia, potassium permanganate, caustic soda, activated carbon, reagent feed, coagulant, flocculants, dispersion, alum, sludge and foams.

  7. Chemical and Petrochemical: various acids, PVDF latex, alcohol, soap, non-aromatic solvents.

  8. Pulp and Paper: latex, kaolin, paper waste sludge, various chemical dosing.

  9. Ceramics: barbotine, mould filling, filter press feeding. Building fibrous mortar, plaster, light concrete, cement flooring.

  10. Surface Treatment: Abrasive waste fluids, acids, alkalis, paints, Electrolytic zinc plating, Copper, Nickel, Tin, Silver and Gold plating, Alcalic zinc, Zinc-iron, Zinc-nickel, Hexavalent Chromium-free plating, Chromates / Passivation, Acid zinc

  11. Anaerobic Digestion: Processed Food & General Waste, Feedstock, Digestate, Waste Sludge’s

  12. Mineral Processing: sludge with viscosity up to 60 000 cps, clay up to 800g/l, particle size: 30 mm, lead sulphate, pyrite, cyanide, various acids.

  13. Agricultural: manure, fertilizer sugar mills, molasses, liquid sugar and various chemicals.

Peristaltic Hose Pump Case Study

One of our distributors were contacted by a customer at an Anaerobic Digestion Plant, having issues with their digestate transfer pumps. The customer was pumping organic waste sludge with abrasive solids, needing a suspension of 25-30%. Their Progressing Cavity Pump was causing a number of issues including clogging, dry running, and failing to deliver the required capacity. The customer was also not supplied with the suitable lifting equipment to work with the pump. Their existing pump was causing unnecessary maintenance costs which could have been easily avoided.

Equipment supplied:

Pump: PT-100 Heavy Duty Pump

Capacity: 30m3 max

Discharge pressure: 5 Bar

Required Suction Lift: 4-5m

Hose: High Pressure Natural Rubber

The customer was advised to change their Progressing Cavity Pump over to a Peristaltic Hose Pump, which could offer a number of various features to help solve the customer’s issues with their existing pump. Our Peristaltic Pumps are 100% leak free, can dry run indefinitely, can provide suction lifts of up to 9.8m vertically and last longer than Progressing Cavity Pumps! The customer was very happy with their decision to take on a Peristaltic Hose Pump from us, and have had no issues since!

There are a number of other reasons we recommended our Peristaltic Pump over any other pump we have available, so why not head to our Case Study section to read the full article on the Anaerobic Digestion Plant.
