KSB ETB Series: Direct-coupled end-suction pump 

The ETB series adopts a horizontal end-suction direct-drive structure, with the pump body directly connected to the motor, eliminating the need for couplings and common bases, achieving efficient conveying within limited space.

In industrial fluid transport scenarios requiring compact installation and stainless steel flow components, the KSB ETB series offers a precise solution. As an important member of the Etanorm family, the ETB series features a horizontal, end-suction, direct-drive design, with the pump body directly connected to the motor, eliminating the need for couplings and common bases, achieving efficient transport within limited space.

KSB ETB Series: Direct-coupled end-suction pump Core Positioning

The ETB series is a direct-coupled pump version of the KSB Etanorm brand, characterized by:

Close-coupled structure: The pump is directly mounted on the motor flange, eliminating the need for couplings, coupling 

covers, and independent bases. This significantly reduces installation space, making it particularly suitable for compact machine 

rooms or integrated equipment environments.

End-suction design: Utilizing a radially split volute, fluid is drawn in axially and discharged radially from the pump's end, conforming 

to EN 733 standards.

Material advantages: Unlike the cast iron materials commonly used in the Etabloc series, the ETB series extensively utilizes 316 stainless

 steel for the pump casing, pump cover, and impeller, offering superior corrosion resistance.

KSB ETB Series: Direct-coupled end-suction pump Model Naming Rules Explained

KSB ETB model naming follows specific rules to help users quickly identify product specifications.

For example, ETB 065-050-200 CCSAV11D201502 B:

Field Meaning

ETB Series Name (Etanorm Direct-Connected)

065 Outlet Diameter (mm)

050 Inlet Diameter (mm)

200 Nominal Impeller Diameter (mm)

CCSAV... Material/Seal/Configuration Code

B Design Version

Another example is ETB 050-032-125, which indicates: Outlet 50mm, Inlet 32mm, Impeller Diameter 125mm

KSB ETB Series: Direct-coupled end-suction pump Performance Parameter Range

Based on common models and product information on the market, the ETB series covers the following range:

Model Specifications | Flow Range | Head Range | Matching Motor Power | Applicable Scenarios

ETB 050-032-125 | 15 ~ 21 m³/h | 23 ~ 19 m | 2.2 kW / 2P | Small-scale water supply and circulation

ETB 065-050-200 | 60 ~ 82 m³/h | 66 ~ 61 m | 15 kW / 2P | Medium-head conveying

ETB 100-080-160 | 191 ~ 259 m³/h | 32 ~ 26 m | 15 kW / 2P | High flow rate, low head

Note: The above are examples of parameters for common models. The ETB series has many specifications, covering

 different flow rates and head ranges. Specific selection should be based on actual operating conditions.

KSB ETB Series: Direct-coupled end-suction pump  Key Technical Features

1. 316 Stainless Steel – Excellent Corrosion Resistance

Unlike the standard Etabloc which uses gray cast iron, the ETB series extensively uses 316 stainless steel (corresponding to KSB 

material codes CC/CCX) for its flow-through components. This feature makes it stand out in the following scenarios:

Industrial fluids containing corrosive media

Sanitary requirements in food, beverage, and beer production

High-purity water delivery in the electronics and semiconductor industry

2. Direct-Mount Structure – Compact and Simple

The pump body is directly mounted on the motor flange, eliminating the need for couplings and common bases:

Small footprint: Suitable for pump rooms with limited space

Easy installation: No complex shaft alignment required

Lightweight: Easy to transport and position

3. Wide Range of Material and Sealing Options

The ETB series offers a variety of mechanical seal configurations to suit different media characteristics. Common sealing materials

 in the spare parts package include BQ1EGG, Q1Q1K9GG/Q1BVGG, etc. Larger models such as ETB 100-80-400 and ETB 125-100-400 

all have corresponding sealing spare parts.

4. Wide Range of Application Industries

According to product information, the ETB series is widely used in the following industries:

Industry Typical Application

General Buildings Water supply pressurization, air conditioning cooling water circulation

Grain and Oil Food Edible oil and syrup conveying

Food, Beverage and Beer Beer, beverage, and dairy production

Electronics and Semiconductors High-purity water and process cooling water conveying

ETB vs Etabloc: How to Differentiate?

ETB and Etabloc both belong to KSB's direct-coupled pump product line. The core differences between them are:

Comparison Dimensions: ETB Series vs Etabloc Series

Material: Mostly 316 stainless steel vs. Mostly cast iron (standard version) or ductile iron (SYT version)

Temperature Range: Under normal operating conditions, Etabloc SYT can reach 350°C

Application Focus: Corrosive media, sanitary requirements; Water supply, cooling, heat transfer systems

Explosion-proof Configuration: Optional by model; ATEX optional

Based on product information, the ETB series is more commonly used in industries with high requirements for corrosion 

resistance and cleanliness, such as food and beverage, electronics and semiconductors, and grain and oil processing.

 The Etabloc/SYT series, on the other hand, has advantages in high-temperature heat transfer fields such as heat transfer 

oil and high-temperature hot water.

Selection and Procurement Considerations

Motor Not Included: ETB pump heads sold on the market typically do not include a motor and must be selected separately. 

The pump shaft size corresponds to a specific power/pole motor (e.g., ETB 065-050-200 with a 15kW/2P motor).

Impeller Diameter Customizable: KSB allows impeller cutting to meet specific customer operating conditions. The original pump

 serial number or actual impeller diameter is usually required before ordering.

Spare Parts Require Serial Number: When purchasing spare parts such as mechanical seals, it is recommended to provide the 

complete pump set model or serial number to ensure compatibility.

Summary: The KSB ETB series is a direct-drive end-suction pump with compact installation and corrosion resistance as its core 

advantages. Its 316 stainless steel flow components, direct-drive design, and wide industry adaptability make it a reliable choice 

for industries such as building construction, food processing, electronics, and chemicals. The ETB series is a preferred choice 

when handling corrosive media or conveying clean water, cooling water, or process fluids in space-constrained environments.
