1.基本规格
规格和型号：
32: inlet and outlet diameters (32mm)
CQ: magnetic drive centrifugal pump (leakage- free design)
25: rated flow rate (25m³/h)
Type: magnetic drive centrifugal pump (no shaft seal, leakage-proof)
Flow range: 15-30m³/h (adjustable)
Head: 25m (maximum up to 30m)
Applicable media:
cyanide solutions (such as sodium cyanide, potassium cyanide), acid and alkali corrosive liquids
2.结构设计
Material of flow-through
parts: Pump casing/impeller: 304/316L stainless steel (corrosion-resistant) or fluoroplastic lining (PTFE/ F46)
Isolation sleeve: Hastelloy or titanium alloy (anti-magnetic eddy current loss)
Sealing method: fully enclosed magnetic coupling transmission (zero leakage)
Bearing lubrication: medium self- lubrication (dry operation needs to be avoided)
3.Power and performance
Motor power: 1.1-2.2kW (380V/50Hz, explosion-proof motor Ex dⅡ BT4 can be equipped)
Speed: 2900r/min(standard)
Working pressure: ≤1.6MPa
Medium temperature:≤80℃ (high temperature type can reach 120℃)
Allowable particles: ≤0.1mm(pre-filter required)
4.Safety protection
Anti-leakage: no mechanical seal, to eliminate the risk of cyanide leakage
Explosion-proof option: Ex dⅡ BT4(suitable for flammable and explosive environment)
Overheat protection: motor temperature rise ≤75℃
automatic shutdown for overtemperature
5.Equipment size and weight
Overall size: ≈500×300×400mm (length×width×height)
Machine weight: 50-80kg (depending on the material)
6.Maintenance points
No idling is strictly prohibited: bearings rely on medium lubrication, idling will cause damage
Regular inspection: Check the magnetic coupling for neutralization every 500 hours
Shutdown treatment: Immediately flush the pump cavity after conveying easy-to- crystallize Medium
Selection suggestions
1. Highly corrosive working conditions (such as high-concentration cyanide liquid): Select perfluoroplastic lining or titanium alloy isolation sleeve models.
2. Explosion-proof requirements: Chemical workshops need to use explosion-proof motors + spark-free structures.
3. Supporting equipment: It is recommended to install a magnetic filter (to prevent iron filings from damaging the magnetic components). If need a cyanide corrosion resistance test report or a customized solution, please specify the specific medium concentration and working conditions.
