8. Frequently Asked Questions (FAQ)

Q1: Does this pump include a motor? What motor is required?

A: No, motor is not included. According to product data, the Micropump L22462 (GC-M35.PF5S.5) is pump end (pump head) only, requiring a separate motor conforming to IEC 71-B5 standard. Additionally, the drive magnet hub must be purchased separately. Recommended speed range is 500-4000 RPM, select appropriate motor power and speed based on required flow. If you need a complete pump+motor combination, please contact our sales team, we can provide a matched solution.

Q2: What is the flow rate? Can flow be precisely controlled?

A: The GC-M35.PF5S.5 is equipped with M35 gear set, displacement 3.48 ml/rev. Within recommended speed range 500-4000 RPM:

Min flow: ~405 mL/min (@500 RPM)
Max flow: ~13.9 L/min (@4000 RPM, 2-pole motor)
4-pole motor (1750 RPM) max flow: ~5.1 L/min Magnetic gear pump flow is proportional to speed, flow can be precisely controlled by adjusting motor speed, with high accuracy and repeatability, suitable for dosing and quantitative transfer applications.

Q3: What is the maximum pressure? Can it be used in high-pressure systems?

A: According to official data, the GC-M35.PF5S.5 has maximum system pressure (MAWP) of 103 bar (1500 psi) and maximum differential pressure of 8.6 bar (125 psi). This means the pump can be installed in high-pressure systems with system pressure up to 1500 psi, but the pump's own generated differential pressure is maximum 125 psi. It is suitable for circulation, metering, and transfer in high-pressure systems, such as high-pressure reactor feed, high-pressure lubrication systems, etc. If higher differential pressure is needed, other series or models may be required.

Q4: Can this pump transfer corrosive liquids? What are the wetted materials?

A: Yes. GC Series magnetic drive gear pumps use multiple wetted material options, standard configuration is 316 stainless steel pump body, gear material options include PEEK, PPS, or PTFE, seal material options include various elastomers. The PF5S in the model represents a specific material/seal configuration (specific material combination to be confirmed by manufacturer). Magnetic drive sealless design combined with chemical-resistant materials makes it ideal for transferring corrosive, toxic, and flammable liquids. If you have a specific liquid to transfer, please provide liquid name and temperature, we can assist in confirming material compatibility.

Q5: What is Suction Shoe design? What are its advantages?

A: Suction Shoe is Micropump's patented design technology. Traditional gear pumps experience high radial forces on gears and shafts under high differential pressure, leading to increased wear and shortened life. Suction Shoe design uses a floating suction shoe component around the gears, utilizing inlet pressure to automatically compensate clearance, reducing wear between gears and pump body, improving volumetric efficiency, and extending service life. Advantages include: high efficiency, low wear, long life, smooth pulseless delivery, and ability to withstand high system pressure. GC Series uses suction shoe design with stationary shafts and two to three helical gears.

Q6: Is this pump self-priming? Does it need priming?

A: Yes, it is self-priming. According to official data, GC Series magnetic drive gear pumps have self-priming capability, dry suction lift ~1.52 m (5 ft), wet suction lift higher. For initial installation, it is recommended to pour a small amount of liquid into the pump (wet start) to reduce dry running and improve priming speed. After normal operation, as long as liquid remains in the pump, it can continuously self-prime. NIPR (absolute inlet pressure) is 180 mBar (2.5 psia), indicating good low inlet pressure adaptability.

Q7: What is the lead time? Can you provide stock?

A: This model is currently in order available status, standard lead time 4-8 weeks (ordered from Micropump USA factory). Magnetic gear pumps are typically custom configurations (materials, seals, ports, etc.), with limited stock inventory. If you have urgent needs, we can try to coordinate stock inventory or expedited ordering. Please indicate required quantity and desired delivery time when inquiring, and we will do our best to coordinate the fastest delivery solution. For large-volume project orders, advance procurement planning is recommended.
