High-Speed ​​Gear Pump for Honey

 

In response to the customer's requirement for a high-speed gear pump for honey, and considering the provided media characteristics (high viscosity, hygiene requirements) and operating parameters (flow rate, pressure, flange size),
the CX-HDD-64 gear pump is a reasonable and significantly advantageous choice. The following is a detailed analysis:
 

 

I. Core Requirement Matching Verification

 

Material Compatibility

Pump Body 316L: Food-grade stainless steel, resistant to acidic components (such as organic acids) and sugar corrosion in honey, meeting FDA and 3A certification requirements, preventing media contamination.

 

Gear Shaft 2507 Super Duplex Steel: High hardness (HRC≥32), resistant to chloride ion corrosion (such as trace amounts of salt in honey), suitable for shear transport of high-viscosity media, with a lifespan more than 3 times longer
than ordinary stainless steel gears.

 

Bearing Silicon Carbide (SiC): Wear-resistant, low-friction, requiring no additional lubrication, preventing honey contamination, and able to withstand short-term high temperatures (such as frictional heat up to 80℃).
PTFE sealing ring + mechanical seal: PTFE has strong chemical corrosion resistance, and the mechanical seal leakage rate is ≤0.1mL/min, meeting sanitary grade delivery requirements.

 

Performance parameters cover:

Flow rate 2-5L/min: Flow rate can be precisely controlled by adjusting the motor speed (1450rpm → pump speed 145rpm) via a reducer (1:10). The gear pump has a volumetric efficiency ≥92%, and its flow stability is superior to centrifugal pumps.

 

Viscosity 14000cp: Gear pumps are suitable for medium to high viscosity media (1-100,000cp). The internal meshing structure (possibly used in CX-HDD-64) has low shear force, avoiding damage to the honey's molecular structure.

 

Low pressure: The gear pump controls pressure through displacement (gear module, number of teeth) and speed. Low speed (145rpm) reduces pressure fluctuations and prevents honey from spoiling due to high-pressure heating.

 

1.5" flange (DN40): Inlet and outlet diameter matching is required; flange standards (such as ANSI B16.5 or GB/T) must be confirmed. (9119) Ensure installation compatibility.

 

Optimized for ambient temperature operation: No special cooling design is required at ambient temperature, but attention should be paid to the potential for temperature rise due to gear friction during honey conveying (it is recommended to monitor the
outlet temperature to ≤60℃). If further cooling is required, a jacketed pump body or external cooling circulation can be used.
 

 

II. Structural Advantages of CX-HDD-64

 

Hygienic design: The entire flow channel is polished to Ra≤0.4μm, with no dead corners, supporting CIP/SIP cleaning to prevent bacterial growth.

 

Modular design facilitates quick disassembly and maintenance, reducing downtime.

 

Low maintenance costs: Silicon carbide bearing life ≥8000 cycles. Mechanical seal life ≥ 5000 hours, maintenance cycle extended by 2-3 times compared to ordinary pumps.

 

Spare parts (such as seals and bearings) are highly interchangeable, reducing inventory costs.

 

Energy saving and quiet operation: The 1:10 reducer design lowers motor load; a 1.1kW motor is sufficient, reducing energy consumption by more than 50% compared to direct drive.

 

Low-speed operation (145rpm) noise ≤ 60dB, suitable for indoor installation.
 

 

III. Supplementary Selection Suggestions

 

Confirm flange standard: Customers need to specify whether the 1.5" flange meets Chinese national standard (GB), American standard (ANSI), or Japanese standard (JIS) to avoid installation incompatibility.

Temperature monitoring: It is recommended to install a temperature sensor to monitor the outlet temperature in real time to prevent honey from spoiling due to high temperatures.

Variable frequency control: If frequent flow adjustment is required, a variable frequency motor (such as the YXVF90S-4 which supports variable frequency) can be selected to achieve stepless speed regulation from 0-5L/min.

Spare parts list: Stock up on vulnerable parts such as PTFE seals and silicon carbide bearings in advance to shorten maintenance time.
