Monoblock Centrifugal Pumps

Detailed Information About Monoblock Centrifugal Pumps

Monoblock centrifugal pumps are centrifugal pumps that offer ease of use and low maintenance requirements thanks to their compact structure where the motor and pump hydraulic body are manufactured as a single unit. Their high-efficiency hydraulic designs provide a wide range of usage in industrial plants and commercial applications.

Advantages of Monoblock Design

• • Compact as the motor and pump are combined in a single body
• • Low maintenance costs, no alignment required
• • Quiet operation and low vibration
• • Durable structure suitable for heavy-duty conditions
• • High-efficiency hydraulic design

Operating Principle

The pump impeller is directly connected to the motor shaft, and energy is imparted to the fluid by the rotation of the impeller. Thanks to centrifugal force, the fluid is transmitted to the discharge line. Due to the single-stage design, efficiency is high and energy consumption is low.

Material Options

• • GG25 cast iron casing
• • GGG40 ductile iron casing (high strength)
• • Stainless steel impeller (AISI 304 / 316)
• • Bronze impeller options
• • Mechanical seal: carbon/ceramic, SiC/SiC, tungsten carbide
• • Motor efficiency classes: IE2 – IE3 – IE4

Application Areas

• • Clean water and network pressurization
• • Industrial process lines
• • HVAC systems (heating – cooling)
• • Irrigation and agricultural watering systems
• • Food, textile, and chemical plants
• • Filtration and auxiliary service pumps
• • Feed pump in booster systems

Technical Capacity Ranges

Monoblock centrifugal pumps are generally manufactured in the range of 1 – 740 m³/h flow rate and 5 – 160 m head pressure. Motor powers range from 0.75 kW to 132 kW. Despite their compact structure, they offer high performance.
