Introduction
A gear pump is a type of positive displacement (PD) pump that transfers fluid through the meshing action of rotating gears. As the gears rotate, a fluid-tight seal is formed between the gears and the pump housing, creating suction at the pump inlet. Fluid drawn into the pump is trapped in the spaces between the gear teeth and the housing, carried around the pump chamber, and discharged through the outlet. Gear pumps deliver smooth, low-pulsation flow at a rate approximately proportional to the rotational speed of the gears.
The CT3001S is a high-performance, low-noise compact variable-speed gear pump. It features a brushless motor and a stainless steel, magnetically coupled pump head, providing stable, near-pulseless flow control. The pump is equipped with a non-touch LCD and push-button controls. Its functions include speed adjustment, start/stop control, and full-speed operation. It also supports a dispensing mode with adjustable speed, run time, interval time, and cycle count. Multiple external control options allow easy integration with other equipment, making the pump suitable for a wide range of laboratory applications.

Tubing & Fitting Set Options
Ordering Notes:
- One tubing-and-fitting set is included.
- When ordering, specify your preferred configuration in the order notes by providing the fitting model or describing the required fitting and tubing specifications.
- For example, “CBT012” includes a set of fittings for flexible tubing and one 2 m length of 24# silicone tubing.
- Replacement tubing note:
- Although the nominal dimensions of 24# tubing differ slightly from 8 mm OD × 6 mm ID, its elasticity allows it to fit securely. Slight dimensional variations are generally acceptable when sourcing replacement silicone tubing, provided the connection remains secure and leak-free.
- PTFE tubing is less flexible and must match the specified outside diameter.
- Please select the appropriate option for your application or contact customer service if additional sets are required.

FAQ
1.What should be noted when placing an order?
Please specify the selected tubing-and-fitting set in the order notes. CBT012, CBT013, and CBT014 are supplied with silicone tubing, while CBT009, CBT010, and CBT011 are supplied with PTFE tubing. If you have any questions, please contact customer service.
2.What type of gear pump is this?
The CT3001S is a variable-speed gear pump with an ABS housing. It includes basic operating functions such as speed adjustment, start/stop, and full-speed operation. It also supports a dispensing mode with adjustable speed, run time, interval time, and cycle count.
3.Does the gear pump support reverse operation?
No. The pump is designed for one-way operation only.
4.Does it have a timing function?
Yes. The CT3001S series supports a dispensing mode with adjustable run time, interval time, and cycle count, which allows timed dispensing.
5.Does it support external control?
Yes. Please note that the buttons will no longer work after switching to external control mode. In this mode, only start/stop and speed adjustment can be controlled externally; the timing function is not supported in external control mode.
6. Does it have an anti-drip setting?
No. The gear pump is unidirectional and is often used with a check valve. It has no back suction function.
7.What should be noted when connecting the fittings to the pump head?
- Use 1/8″ NPT male fittings. Clean the male and female threads thoroughly, leaving no residue, and ensure that the threads are not damaged or deformed.
- Starting from the second thread, wrap PTFE thread seal tape clockwise around the male thread for two tight turns. Cut off the tape and press the end firmly against the thread.
- Screw the fittings into the inlet and outlet ports of the pump head and tighten them with a wrench. Do not overtighten, as this may damage the fittings or pump head.
8.What should be noted when using the pump with a check valve?
- Install the check valve vertically in the direction of flow, with the arrow on the valve pointing upward.
- Keep the liquid level in the inlet-side container below the check valve. Ideally, the suction tubing should run horizontally or slope slightly upward toward the pump head.
- Movement of the tubing can create tension, affecting the transferred volume and dispensing repeatability. Secure the outlet tubing and check valve to the outlet bracket.
- To further reduce dripping, we recommend attaching a filling needle to the outlet tubing.
9. Does it support flow calibration?
No. This model is speed-adjustable type. If flow calibration is required, please select the dispensing model.
