Hello, could anyone please advise on a good lubricant for a peristaltic pump hose (the one between the rollers) ? I am using a Seko pump with a Pharmed BPT (TPE) hose for acid injection. I've seen conflicting information online: some sites mention not to use silicon-based lubricants, some say to use pure silicon grease, and others recommend glycerin or water based options, etc.

what do you guys typically use for this ? will the typical Jack 327 Pool gasket Lube damage those TPE hoses ?

Also, if I need a specific one, can you guys recommend a brand / website where you can buy a small amount? I found some places that specifically sell peristaltic hose lubricant but they only sell that the bucket...

Thanks!
 
In case someone else uses a Pharmed BPT (TPE) tubbing .... Pharmed said Glycerine based (USP Grade) lubricant is the one needed for that particular model..... Seko said they don't use that kind of tubing in their pumps ( the reseller SOLAXX replaced it with a pharmed )

PharMed® BPT Biocompatible Tubing.

This tubing is formulated to withstand the rigors of peristaltic pumping action while providing the biocompatible fluid surface required in sensitive applications.

It is suitable for fermentation, synthesis, separation, purification, control systems, process monitoring, and protecting sensitive cell cultures.

Independent tests show it's safe for use in sensitive cell culture applications.

It has very good general chemical resistance and excellent acid, alkali and oxidation resistance.

Opaque to visible and UV light, it helps protect sensitive fluids.

Less permeable than silicone tubing
Superior flex life characteristics
Excellent wear properties & low particulate spallation
Autoclavable
Durometer hardness (shore A): 64
Temperature range: -60°F to 275°F
Meets the requirements of USP 88 Biological Reactivity Test, In Vivo - Class VI
Priced per foot; sold in 5' intervals - 25' standard length (±6" cut tolerance)

More About this Item
A combination of biocompatible fluid surface and exceptional flex life makes PharMed BPT tubing ideal for transferring sensitive bioprocessing fluids.

Formulated for use in the pharmaceutical and biotechnology industries, it is ideal for use in cell harvesting, media processing, vaccine manufacturing, aseptic filling, and diagnostic testing applications.

The PharMed BPT tubing withstands repeated CIP and SIP, simplifying cleaning and sterilization.

Tubing can be used with most commercial cleaners and sanitizers; autoclave up to five cycles or use gamma irradiation without affecting overall service life.

This specially formulated tubing features exceptional flex life characteristics and excellent wear properties to outlast silicone in peristaltic pumps and help minimize downtime due to tubing failures.

The low permeability characteristics provide protection for sensitive fluids from gas ingress. Opaque tubing protects light-sensitive fluids from visible and UV lights.

Warning: This product is not approved or intended for, and should not be used for, medical, clinical, surgical or other patient-oriented applications.
 
PharMed BPT tubing, a thermoplastic elastomer (TPE) used in peristaltic pumps, generally does not require specific lubrication for optimal performance, but some manufacturers may recommend a silicone-based lubricant for easier threading or to prevent sticking during initial setup.

Here's a more detailed explanation:

PharMed BPT Properties:

PharMed BPT is a polypropylene-based TPE known for its flexibility, chemical resistance, and suitability for food and beverage applications.

Lubrication Considerations:

While PharMed BPT is generally considered self-lubricating, some manufacturers might suggest using a silicone-based lubricant to aid in threading the tubing onto the pump rollers or to prevent sticking during initial use.

Alternative Lubricants:

Avoid using oil-based lubricants, as they can degrade the tubing.

Manufacturer Recommendations:

Always refer to the specific instructions provided by the peristaltic pump manufacturer for the most accurate guidance on tubing lubrication.
General Advice:

If you encounter difficulty threading the tubing, a light application of silicone-based lubricant can be helpful.
