What is the FL-PH cast iron peristaltic pump for?
In a peristaltic pump the rollers progressively squeeze a rubber tube and push the product towards the outlet. This pressure and vacuum effect drives it without exerting any direct mechanical stress on it, and because the only contact between the product and the pump is the tube, it handles low, medium or high viscosity fluids, abrasive fluids and fluids containing solids.
InoxMIM designed the FL-PH in cast iron to broaden the range of applications for these pumps: water treatment, chemicals, paper, mining, food, pharmaceuticals and cosmetics. Its design aims for more flow and pressure and a longer tube life. It is reversible and self-priming in both directions, can run dry and, having no sealing system, operates with total leak-tightness.
This is the right pump if…
- You pump mud, sludge, sediments, carbonates or coarse suspensions of coal.
- You move chemicals such as dyes, glues, resins, paints or inks without them touching mechanical parts.
- You need to reverse the direction of rotation to empty lines or change product without mixing.
- The pump may run out of product: the FL-PH can run dry.
Choose other equipment if…
- You work in a winery or food plant and need more flow, up to 52,000 L/h, in stainless steel: the FL-PT peristaltic pump is better.
- You receive whole grapes or tomatoes and want to tip them into a hopper: the FL-PT with hopper is better.
- You need to deliver at more than 8 bar: the FL-ERB progressive cavity pump is better, up to 24 bar.
- It is a clean, low-viscosity liquid at high flow rates: a centrifugal pump is enough.
Applications by industry
Some of the products the FL-PH handles:
Water, mining and construction
Mud, sludge, sediments, carbonates, coarse coal suspensions, mortars, concrete and fibre cement.
Chemicals, paper and paints
Cellulose, dyes, colourants, glues, resins, detergents, fertilisers, paints, inks, enamels and pigments.
Food industry
Milk, yoghurt, juices, pulps, jams, wines, mayonnaise, fats and used oil collection.
Cosmetics and pharmaceuticals
Creams, gels and concentrates, with no contact between the product and mechanical parts.
Features and benefits
Only the tube touches the product
No contact with mechanical parts: handles abrasive, viscous or solids-laden products.
Reversible and self-priming
Self-priming in both directions of rotation: avoids product losses and mixing between fluids.
Dry running
It can run without product without being damaged.
Total leak-tightness
It has no sealing system, so there is no mechanical seal that can leak.
FDA natural rubber tube
Abrasion-resistant and multi-layered, designed for strength and durability.
Simple maintenance
Roller adjustment and easy assembly and disassembly for maintenance tasks.
Models in the series
Choose the model by the flow rate you need. Both sizes work at up to 8 bar.

Frequently asked questions about the FL-PH cast iron peristaltic pump
What flow rate and pressure does the FL-PH deliver?
The FL30PH delivers up to 2,000 L/h and the FL40PH up to 3,000 L/h, both with a maximum working pressure of 8 bar and a self-priming pressure of -0.7 bar. Maximum power ratings are 1.1 and 2.2 kW.
What products can it pump?
Low, medium or high viscosity products, abrasive or containing solids: mud, sludge, cellulose, carbonates, mortars, dyes, glues, resins, paints, fats, milk, yoghurt, pulps, jams, creams or latex, among others. The product only touches the tube, never the mechanical parts.
Can it run dry?
Yes. Its design allows it to run without product, and as it has no mechanical seal there is no component that can be damaged by running empty.
When is a stainless steel body advisable?
The FL-PH is made as standard in GG-25 grey cast iron and, as an option, with a cast body in AISI 316. The choice depends on the product, the working environment and the industrial or food finish you need; contact us about your case.
What temperature can it withstand?
With the natural rubber tube, from -20 to 80 °C. With other tube materials it can reach up to 150 °C.
What maintenance does it need?
The tube is the wear part and is replaced when it loses elasticity. The pump has roller adjustment and is easy to assemble and disassemble, which simplifies tube changes and inspections.
