SK165 Peristaltic Pump
Rollers squeeze a flexible tube, so the liquid touches nothing but the tube and maintenance means fitting a new one.
Overview
What This Pump Does
The SK165 peristaltic pump, also called a tube pump, is designed mainly for analytical instruments and feeding equipment. Tube thickness is 1 mm or 1.6 mm, maximum tube size is 4.8 mm, maximum speed is 200 rpm and maximum flow is 165 ml per minute.
It is used in analytical equipment, car wash equipment, food processing, laundry equipment, printing equipment and warewashing equipment, where a simple structure and quick tube changes matter more than high flow.

Key Benefits
What The Tube Principle Gives You
Only The Tube Is Wetted
Chemical compatibility becomes a tube question instead of a whole pump question.
Tubes Change In Minutes
Easy tube replacement means service is a consumable change rather than a pump rebuild.
Quiet And Simple
Low noise and a simple structure suit equipment that sits in a laboratory or a public area.
Self Priming And Dry Run Tolerant
The pump lifts from an empty line and is not damaged when the supply runs out.
Application Scenarios
Where It Is Installed
Analytical Equipment
Feeding sample and reagent streams inside instruments at a repeatable rate.
Washing And Warewashing
Dosing detergent and chemistry in laundry, warewashing and car wash equipment.
Food And Printing Machines
Metering flavour, colour or ink where the liquid must not touch a pump body.
Who It Is For
- Instrument builders
- Commercial washing equipment manufacturers
- Food and printing machine builders
- Laboratories needing a simple dosing pump
Problems It Solves
Chemicals destroy conventional pumps
With only the tube in contact, aggressive chemistry is handled by choosing the right compound.
Cross contamination between liquids
Changing the tube changes the entire wetted path in minutes.
Pumps fail when a tank empties
Dry running does no damage, which suits intermittent dosing duty.

Technical Data
Published SK165 data. Delivered flow depends on tube bore and speed, so state the rate you need rather than the pump model.

Materials And Process
What Goes Into Every Unit
Materials
- Flexible tube selected for the chemical
- Housing suited to bench and machine mounting
- Rollers matched to the tube size
Manufacturing And Assembly
- Head assembly and roller setting
- Tube fitted and flow checked
- Run test before packing
- Documentation and spare tube supply
Quality Control
- Flow verified against the tube fitted
- Noise and run check before dispatch
- Test record available with the order
Customization Options
- Tube material for the chemical
- Fixed or variable speed drive
- Mounting for bench, panel or machine
- Supply voltage to suit the equipment
Compared With Other Options
| Magnetic drive gear pump | The gear pump gives smoother flow at higher pressure on clean liquid. The tube pump wins on aggressive chemistry and dry running. |
|---|---|
| Diaphragm dosing pump | A diaphragm pump has valves that gas lock. A tube pump passes gas straight through. |
Use Guide
Setting Up A Tube Pump
Pick The Tube
Choose bore and compound for the chemical and the rate. A larger tube run slower usually lasts longer.
Route The Lines
Keep suction short and avoid restrictions, which make the tube work harder on every revolution.
Calibrate
Measure delivered volume at the working speed and use that for control.
Change On Schedule
Record tube changes and set an interval from your own evidence rather than waiting for a failure.
Answers
SK165 Peristaltic Pump FAQ
What is the maximum flow?
165 ml per minute at up to 200 rpm, with maximum tube size 4.8 mm.
Which tube thicknesses are available?
1 mm and 1.6 mm for selection.
Where is this pump used?
Analytical equipment, car wash equipment, food processing, laundry equipment, printing equipment and warewashing equipment.
Can it run dry?
Yes, without damage, which is why it suits intermittent dosing.
How often do tubes need changing?
It depends on speed and chemistry. Keep spares on site and set an interval at commissioning.
