LKHI
The Alfa Laval LKHI Centrifugal Pump for 16 bar Inlet Pressure is a is a premium pump for use in hygienic applications with inlet pressures up to 16 bar. To increase process productivity, it is distinguished by high efficiency, gentle product treatment, chemical resistance, and a wide range of flow rates, pressures and options. Precision-engineered, the LKHI pump delivers greater energy efficiency than similar premium pumps.
Increase process productivity while providing high efficiency and gentle product handling
- 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
- High inlet pressure: designed for inlet pressures up to 16 bar and can therefore be used in systems with higher pressure rating
Its optimized design, premium motor, tight tolerances and advanced impeller design make it an efficient inlet pressure pump, minimizing recirculation and reducing energy consumption. Designed for inlet pressures up to 16 bar and for Cleaning-in-Place (CIP), the Alfa Laval LKHI is ideal for higher pressure hygienic applications within the dairy, food, beverage and personal care industries that require gentle product treatment and reliable operation. The LKHI pump is available in nine sizes to handle capacities up to 240 m3/h and provide differential pressures up to 8 bar at 50 Hz.

How does the LKHI centrifugal pump work
Pump range
LKH centrifugal pumps are currently available in 13 sizes to handle capacities up to 500 m3/hour and pressures up to 190 H/(m). Options include types of shaft seals, flushing arrangements and elastomers.
These special versions are also available for specific duties:
LKH UltraPure for biotech and pharmaceutical applications
This pump is the premier choice for biopharm applications that demand high efficiency, exceptional cleanability, contamination safety, robust design and low maintenance. For these reasons, it is also an excellent choice for some personal care processes. Alfa Laval UltraPure pumps are supplied with the comprehensive Q-doc documentation package.
For the biotech and pharmaceutical industry:
LKH UltraPure (Premium centrifugal pump)
LKHPF for high-pressure applications
With heavy-duty pump casing and backplate, high-pressure internal seals and multiple heavy-duty studs, these pumps are capable of handling high inlet pressures up to 40 bar (600 PSI). Tough under pressure, the LKHPF is ideal for demanding nanofiltration and reverse osmosis filtration installations.
LKH Multistage for high outlet pressures
Suitable for high-pressure applications with low capacity requirements, this compact, efficient pump is ideal for use in reverse osmosis and ultrafiltration processes. One pump can replace up to three booster pumps on a production line, saving valuable floor space.
LKHSP for self-priming applications
This self-priming pump is designed for use as a CIP return pump or for tank drainage since it is capable of transporting products with entrained gas.
LKHex for applications in explosive environments
Engineered for use in potentially explosive environments, the LKHex is available in nine sizes and conforms to the provisions of ATEX directive 94/9/EC Group II, Categories 2 and 3.
LKH Evap is a dedicated evaporator pump
Based on the LKH range, the LKH Evap is a tailored evaporator pump supported by strong and extensive documentation, including a comprehensive vacuum curve package. It features a special scraper impeller ClearFlow that solves the product build-up problem in high solids applications, which considerably can prolong production time between cleaning.
Unique impeller design
The semi-open impeller with a special vane design ensures particularly low NPSHr (Net Positive Suction Head required), making it an essential feature in high inlet pressure pumps to prevent cavitation and minimize mechanical damage.
Balance holes in the impeller enhance circulation around the shaft seal and reduce axial forces. This minimizes wear on the shaft seal and motor bearings.
External 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.
Optimised shaft seal
One shaft seal fits a wide pump range. The exact same LKH single shaft seal fits 11 models of LKH pumps as well as all models of the SolidC pump. The LKH seal also has the option of single or double flushed, which can be interchanged in minutes with just a few extra components.
This standardization reduces inventory and makes wear parts replacement quick and easy.
Compression couplings
Another notable feature is the compression coupling. This securely attaches the stub shaft to the motor shaft with precision alignment. Setup is simple, operations secure and noise and vibration minimized. What’s more, the coupling helps prolong the service life of both shaft seal and motor.

A premium performer
As Alfa Laval’s premium range of centrifugal pumps, the LKH centrifugal pumps are distinguished by high efficiency, low energy consumption, several options, and a wide range of flow rates and pressures.
High efficiency
A precision-engineered pump and motor provide high efficiency and gentle product treatment. The robust design and tight tolerances together with the advanced impeller design minimize recirculation and ensure the efficient transfer of energy.
Optimal pump design
The impeller design ensures efficient and gentle handling of the product as it moves through the pump. This ensures product integrity and minimizes NPSHr (Net Positive Suction Head required).
Low energy consumption
Making pump energy use more efficient presents huge potential for energy savings. The optimized pump design and premium motor of Alfa Laval LKH centrifugal pumps often deliver greater energy efficiency than similar premium pumps and up to 50% compared to similar mid-range pumps.
Cleanability and hygienic design
The key is the attention to detail. Controlled compression gaskets, crevice free internals, an external mechanical seal, and an optimised impeller with balancing holes all ensure that the pump is truly cleaned during a time effective CIP cycle. Perfectly aligned components and joints with O-rings tightened to a predefined compression minimize the elastomer product contact surfaces, which also safeguards hygiene.
External shaft seal – hygienic and serviceable
By positioning the shaft seal outside the pump, difficult-to-clean components do not come into direct contact with the product. In addition, the front-loading design enables quick and easy replacement, providing more uptime with lower maintenance costs. Interchangeable single, flushed and double seals simplify spare parts inventory.
Warranty
Alfa Laval provides a three-year warranty for all non-wearing parts, provided genuine parts are used.
