Standard design

The Unique SSV Standard is available in a one- or two-body

configuration, with easy-to-configure valve bodies, plugs,

actuator and clamp rings. The valve can be configured as a

shutoff valve with two working ports or as a changeover valve with

up to five ports.

To ensure flexibility, the valve seat that sits between the two

bodies in the changeover version is provided for assembly. The

valve seals are optimized for durability and long service life

through a defined compression design. The actuator is connected

to the valve body using a yoke, and all components are

assembled with clamp rings.

The valve can be fitted with Alfa Laval ThinkTop V-series for

sensing and control of the valve. See ThinkTop datasheets for

further details.

Using the Alfa Laval Anytime configurator, it is easy to customize

to meet virtually any process requirement.

Working principle

The Alfa Laval Unique SSV Standard is operated by means of

compressed air from a remote location. The actuator smooths

operation and protects process lines against pressure peaks,

while directing or diverting fluids. The valve can be controlled

using an Alfa Laval ThinkTop®.

How does the SRU rotary lobe pump work?

Consistent performance

The reliable SRU rotary lobe pd pump features a front cover seal with defined

compression, rotor nut retention design, drainable pump head and ultra-clean surface

finishes to maximize uptime and minimize contamination risks.

Greater flexibility

Modular design and a broad range of models, capacities and options provide versatility

to meet specific application and process requirements.

Low maintenance

A robust gearbox construction with heavy-duty shafts, torque locking assemblies and

tapered roller bearings minimizes maintenance requirements.

Certification, specifications, and standards

SRU rotary lobe pumps meet the requirements of global hygienic standards, including

3-A Sanitary Standards and FDA standards. The pumps can also meet ATEX requirements

for use in explosive environments.

The Alfa Laval SRU rotary lobe pump is a positive displacement pump for gentle

handling of sensitive process fluids in demanding hygienic applications.

High-precision rotors and low-shear, low-pulsation pumping action ensure reliable,

continuous performance and superior energy efficiency. Its contamination-proof

design ensures compliance with the most stringent hygienic design standards

and the requirements for Cleaning-in-Place (CIP) and Sterilization-in-Place (SIP)

validation.

High pump efficiency and gentle product treatment optimize

contamination-free transfer of viscous products

• Maximize uptime through consistent performance

• Raise product quality due to gentle, low-shear product handling

• Increase product safety and quality due to hygienic design and validated

cleaning processes

• Add more process flexibility with versatile handling and efficient pumping of

various products, including viscous media

• Low-maintenance design – a robust gearbox construction with heavy-duty shafts,

torque locking assemblies and taper roller bearings minimizes service

The Alfa Laval SRU rotary lobe pump provides high-efficiency fluid transfer, maximizing

uptime while minimizing contamination risks and maintenance costs.

Its low-pulsation, low-shear pumping action transfers media of varying viscosities with

ease. Modular design provides great flexibility to tailor a pump to meet specific process

requirements.

Available with 12 different pump head displacements, the SRU rotary lobe pump handles

flow rates up to 106 m3/h, differential pressures up to 20 bar and temperatures up to

200°C.

Benefits

• Energy efficient: superior efficiency resulting in reduced energy

consumption and CO2 footprint.

• Hygienic: designed according to the most stringent hygienic

design standards and with verified, effective CIP cleanability.

• Wide performance envelope: reduce need for parallel and

serial pump installations and ensure pump operating with high

efficiency.

• Maximized uptime and reduced maintenance costs: robust

mechanical design and ease of maintenance with modular

front-loading seals.

Standard design

All media contacting steel components like pump casing,

impeller, impeller nut and backplate are in W. 1.4404 (AISI 316L).

A stainless steel shroud protects the motor and four adjustable

stainless steel legs support the complete unit.

A compression coupling securely attaches the stub shaft to the

motor shaft with precision alignment, and the semi-open impeller

with a special vane design ensures efficient and gentle handling

of the product as it moves through the pump.

As standard, the LKH pump is equipped with a single mechanical

shaft seal but is also available with a single flushed or a double

mechanical shaft seal. The front-loading shaft seal, with the

spring and washers mounted on the atmospheric side, makes

maintenance fast, easy and inexpensive. It takes just a few

minutes to replace the shaft seal. In addition, the balanced design

minimizes the risk of seal opening during unforeseen pressure

shock.

Introduction

Standard design

All media contacting steel components like pump casing,

impeller, airscrew, front cover, recirculation pipe and backplate are

in W. 1.4404 (AISI 316L). A stainless steel shroud protects the

motor and four adjustable stainless steel legs support the

complete unit.

A compression coupling securely attaches the stub shaft to the

motor shaft with precision alignment, and the semi-open impeller

with a special vane design ensures efficient handling of the

product as it moves through the pump.

As standard, the LKH prime pump is equipped with a single

mechanical shaft seal but is also available with a double

mechanical shaft seal. The front-loading shaft seal, with the

spring and washers mounted on the atmospheric side, makes

maintenance fast, easy and inexpensive. It takes just a few

minutes to replace the shaft seal. In addition, the balanced design

minimizes the risk of seal opening during unforeseen pressure

shock.

Benefits

• Energy efficient: superior efficiency resulting in reduced energy

consumption and CO2 footprint.

• Hygienic: designed according to the most stringent hygienic

design standards and with verified and effective CIP

cleanability.

• Quiet: operates very quietly compared to other self-priming

pumps improving the working environment.

• Reduced capital investment: designed for Cleaning-in-Place

(CIP) duties containing entrained air but can also pump

product reducing need for additional pump.

Working principle

On applications where the pumped media contains a mixture of

air and liquid in the suction line, airscrew rotation causes the

formation of a continuous liquid ring within the canister. Due to the

eccentric position of the canister relative to the airscrew, an air

chamber forms between the liquid ring and the airscrew, which

separates into air pockets between the air-screw vanes.

The continuous rotation of the air-screw forces air pockets

through the canister into the suction stage of the impeller which

are then pumped out via the discharge.

Liquid is returned from the discharge via the recirculation pipe into

the canister to ensure the liquid ring is maintained at all times.
