Model Analysis
HZV: may stand for Submersible Pump (H) + Vertical Mounting (Z) + Special Design (V)
40: Rated flow rate (40m³/h)
P: may represent cast iron material (P for cast iron, S for stainless steel, etc.)
Type: Submersible centrifugal pump (suitable for sump, drainage pit, etc.)
Installation method: fixed/mobile (with automatic coupling device)
2.Performance parameters
Flow rate (Q): 20-50m³/h (optimal operating point 40m³/h)
Head (H): 10-25m (adjusted according to the impeller series)
Power (P): 37.5kW (commonly used 4kW/5.5kW, 380V -50Hz)
Speed: 1450-2900r/min (4-pole/2-pole motor)
Maximum diving depth: ≤10m (depending on cable length and sealing level)
3.Structure and material
Pump Material:
Cast iron (HT200) / stainless steel (304/316L, corrosion resistant)
impeller:
Closed/semi-open impeller (cast iron/stainless steel/nylon reinforced material)
Anti-clogging design (suitable for sewage containing impurities)
Sealing system:
Double mechanical seal (SiC/Carbon pairing)
Oil chamber leakage sensor (optional)
4.Applicable medium Liquid Type:
Clean water, rainwater, sewage (containing a small amount of solid particles ≤20mm)
Mildly corrosive liquids (pH 410, stainless steel models can be extended to pH 212)
Liquid temperature: ≤40℃ (high temperature requires special design)
Solid content: ≤5% (weight ratio)
5.Control system (optional)
Automatic start and stop: float switch/liquid level sensor control
Protection function:
Overload, phase loss, water leakage alarm (IP68 protection level)
Dry running protection (need to be matched with sensor)
6.Taille et poids de l'équipement
Outlet diameter: DN50-DN80 (flange connection, standard GB/T 9119)
Machine weight: 50-120kg (depending on material and power)
Overall dimensions (diameter × height): ≈φ200-300mm×500-800mm
7.Special configuration (optional)
Explosion-proof model: Ex dⅡ BT4 (suitable for flammable and explosive environments)
Wear-resistant design: impeller sprayed with tungsten carbide (for sandy water)
Remote monitoring: 420mA signal output (integrated IoT module)
Key Considerations
1.Selection points:
When there are fiber impurities, a cutting device must be installed (such as HZV40PC model)
For highly corrosive environments (such as seawater), 316L stainless steel is recommended.
2.Installation requirements:
The bottom is ≥0.5m from the bottom of the well to avoid sand inhalation
The automatic coupling device must be used with the guide rail
3.Maintenance cycle:
Check the seal every 6 months
Long-term out of use requires hoisting and storage
Typical application scenarios
Municipal Engineering: Drainage of underground garage water collection well
Industry: factory waste water pits, cooling water recovery
Construction: foundation pit dewatering, tunnel drainage
