What Affects Compact Peristaltic Pump Price? Flow Rate, Pump Head, Tubing?

What makes one small tube pump cost more than another? The compact peristaltic pump price relies on six factors. Flow range, pump head, tube size and type, controls, build, and warranty are some of these. All of these alter the ultimate price.

Innofluid Co., Ltd. has 20 years of R&D work on peristaltic pumps. No pricing on its product pages, just specifications. So your quote relies on the arrangement you choose.

LabQ/KT15, LabT/KT15, and LabK/MicroPump are three compact models covered in this guide. It is related to the actual specifications of each cost factor. What to submit for a clear quote ends this section.

What Sets the Compact Peristaltic Pump Price?

The whole configuration, not only the motor, determines the compact peristaltic pump price. The drive matters. The pump head matters. The tube matters. The controls matter. Together, they form a quote. A modification in one part may affect the final figure. 

For example, increasing the tube size increases the top flow rate. Also, an additional control signal adds to the build. Therefore, the quote always reflects your entire configuration, not a list price. These parts are known for helping you compare quotes from vendors fairly.

Why Quotes Follow the Configuration

One KT15 drive may run five tube diameters. Each size will have a varied flow range. So each size might give you a different quote. A reputable compact laboratory peristaltic pump supplier will question you about your job initially. 

It will ask you about your fluid, your goal flow and control requirements. This helps match the correct tube to the right head. You can see all the models in the compact laboratory peristaltic pump range.

Three Innofluid Compact Models Compared

How Flow Rate Range Shapes the Quote

Speed Range Decides the Flow Ceiling

The amount moved in a single revolution multiplied by pump speed is the flow rate. The KT15 head has a 25# tube that moves 0.933 mL / revolution. The top flow is 326.55 mL/min when the speed is 350 rpm.

Speed changes are .1 rpm increments on all three models. It is useful in small dosages. You will get this in writing from any variable speed peristaltic pump supplier.

Matching Flow Needs to the Right Drive

With some space to spare, the best drive covers your demand. KT15 models can go up to 326.55 mL/min. LabK stops at 63.96 mL/min.

The LabK page lists low power use, quiet running and continuous dosing. If you need less than 64 mL/min, start with the lightweight LabK micro pump. A low flow peristaltic pump manufacturer can help you check this.

Paying for flow you never use only raises the compact peristaltic pump price. It adds cost but no real value.

Why the Pump Head Changes the Cost

The pump head changes the cost because it sets which tubes fit. It also sets how much liquid moves in each turn. Innofluid's compact models use two heads: KT15 and MicroPump. KT15 takes five tube sizes and suits higher flow. MicroPump takes four tube sizes and suits low flow dosing.

KT15 Head: Five Tube Sizes, One Channel

The KT15 is a single-channel head. It takes five tube sizes. These figures come from the LCD-screen LabQ/KT15 pump page. LabT/KT15 lists the same flow ranges.

Here is a simple check. Say you need 50 mL/min. A 14# tube needs about 321 rpm, which is close to top speed. A 19# tube needs only about 175 rpm. That leaves room. Innofluid's tubing guide also says higher speed shortens tube life.

MicroPump Head for Compact Dosing Work

The MicroPump head is used on LabK. It takes four tube sizes:

1×1 tube: 0.004-6.38 mL/min

2×1 tube: 0.014-21.45 mL/min

3×1 tube: 0.031-47.26 mL/min

4×1 tube: 0.042-63.96 mL/min

Innofluid does not list mL per turn for this head. So check your flow against these ranges. Picking the smallest head that fits keeps the compact peristaltic pump price in line with the job.

Tubing Size, Material and Running Cost

Tubing affects both the first quote and the running cost. Tubes wear out over time, so you must replace them. The tube type sets how long it lasts. Silicone, PharMed and Tygon tubes each suit different fluids. Picking the right size and type early helps you avoid extra costs later.

How to Read Tube Size Codes Correctly

A tube number is a size code, not a grade. On the peristaltic pump tubes and accessories page, 13# means a 0.8 mm bore. 25# means a 4.8 mm bore. The same code means the same size in silicone, PharMed and Tygon.

All KT15 tubes have 1.6 mm wall. So only the bore determines flow range.

Tubing Life and the Long-Term Budget

The pump price is simply one portion of your budget. Tubing is a recurring expense. LabK employs extended life PharMed tubing which is simple to repair.

A inexpensive tube that breaks down regularly might cost you more in one year. A better, longer-lasting tube can save you money.

Innofluid's silicone, PharMed and Tygon comparison says PharMed BPT lasts up to 30 times longer than plain silicone in a pump. On long runs, this can matter more than the compact peristaltic pump price itself.

Controls, Signals and Display Options

Control features add to the quote when your work needs timing, automation or remote control.

Timed Dispensing for Metering Tasks

LabQ has multi-cycle timed dispensing from 0.1 s to 9999 h. It can repeat 1 to 9999 times. Set the repeat count to "0" for nonstop running. This covers what most buyers want from a peristaltic metering pump manufacturer.

The LabT/KT15 OLED timer pump has a 0-9999 s timer. It also has a 0-999° back-suction angle. Back-suction turns the rotor back a little after a run. This helps stop drips. A peristaltic dosing pump supplier should tell you which timer fits your task.

External Control Signals and RS485 Links

0-5V and 4-20mA: on all three models

0-10V: standard on LabQ, optional on LabT and LabK

RS485 with Modbus: on all three models

Extra ports: USB on LabT, open-collector output on LabQ

Each extra signal adds to the compact peristaltic pump price. So list every signal you need in your first message.

Size, Power and Build Details to Compare

Footprint and Weight on a Busy Bench

LabQ is the largest of the three. It measures 188 × 128 × 135 mm. LabT and LabK share a 180 × 115 × 125 mm body.

LabQ and LabT use under 30 W. LabK runs on DC 24V/1A with a power adapter. When you compare a benchtop peristaltic pump manufacturer or a small peristaltic pump supplier, check these numbers against your bench space and power.

Warranty Terms and Working Conditions

All three models come with a 3-year warranty. Each one works at 0-40°C and below 80% humidity. LabQ and LabK are rated IP31. LabT does not list an IP rating. The LabK keypad is rated for 300,000 presses.
