Vertical Monoblock Sewage Pump

The Vertical Monoblock Sewage Pump is designed specifically for wastewater with high solids content. It has strong anti-clogging performance, stable operation, and is widely applicable to municipal, industrial, and commercial wastewater treatment.

 

For example:

NVS50.125A-M2/1.5V-AG-C

NVS - Series name

50 - Nominal diameter (mm), e.g., DN50

125 - Impeller code

A - Impeller variation code (A, B, C distinguish different impeller cuts)

M - Motor configuration

2 - Motor stage

1.5 - Motor power (kW)

V - Motor type: V = Variable frequency, E = Explosion-proof; standard motors have no special code

A - Impeller material: A = Alloy steel, S = 0Cr19Ni9 stainless steel, O = Other materials

G - Pump body material: D = QT500, G = HT200, S = 0Cr19Ni9 stainless steel, O = Other special materials

C - Cutter head option: C = With cutter, N = Without cutter

 

High-Efficiency Sewage Discharge

Single-stage, single-suction vertical pump body + semi-open spiral impeller, wide flow channel, excellent solid flowability, smooth sewage discharge and less clogging.

 

Optional Hardened Cutting Head

Quickly hardened and tempered cutting head can cut fibers and debris, improving sewage discharge efficiency and reducing manual cleaning.

 

Double-Layer Seal

Standard mechanical seal, optional IVS special seal, improving leak-proof capability and adapting to highly corrosive or sand-containing conditions.

 

Corrosion-Resistant Materials

Stainless steel impeller is corrosion-resistant, suitable for mildly corrosive wastewater with pH 5–9, and has a long service life.

 

 

Production Capacity: 15,000㎡ factory area, 5 production lines, annual output of 10,000 water pumps and 5,000 blowers.

 

Quality Assurance: ISO 9001 and CE/TUV certified, full-process quality control, 100% finished product qualification rate.

 

Technology R&D: 20 engineers and 10 technicians, 15 patents, supporting new product development and non-standard customization.

 

Supply Chain and Inventory: 50+ long-term suppliers, key components manufactured in-house, common raw material inventory ≥3 months of production.
