Different models for different duties

Several LKH pump models are available to meet varied process requirements:

	LKH UltraPure for biotech and pharmaceutical applications
	LKHPF for high-pressure applications*
	LKH Multistage for high outlet pressures*
	LKHSP for self-priming applications*
	LKHex for explosive environments*
	LKH Evap for dedicated evaporator pump*

LKH pumps are available in 13 sizes to handle capacities up to 500 m³/hour and pressures up to 190 H/m. Options include shaft seals, flushing arrangements and elastomers.

Available sizes: –5, –10, –15, –20, –25, –35, –40, –45, –50, –60, –70, –80, –90

How the LKHPF High Pressure Pump Works

All product-contact parts including the pump casing, impeller, impeller nut and backplate are made from W. 1.4404 (AISI 316L) stainless steel. The motor is protected by a stainless steel shroud and the complete unit is supported by four adjustable stainless steel legs.

A compression coupling securely connects the stub shaft to the motor shaft with precise alignment. The semi-open impeller with a special vane design delivers efficient yet gentle product handling throughout the pumping process.

The LKHPF pump is supplied as standard with an internal single mechanical shaft seal with the option for a flushed shaft seal. The flushed version uses a durable lip seal as the secondary seal. The front-loading shaft seal design enables quick easy and cost-effective maintenance. Shaft seal replacement can be completed in just minutes. Its balanced design also reduces the risk of seal opening during unexpected pressure surges.

With a heavy-duty pump casing and backplate, high-pressure internal seals and multiple heavy-duty studs the pump is built to withstand very high inlet pressures.

FAQ

Q1: What is the Alfa Laval LKHPF pump?
The LKHPF is a high pressure centrifugal pump designed for hygienic filtration duties, capable of handling very high inlet pressures while ensuring gentle product treatment.

Q2: How does the LKH Multistage pump differ from LKHPF?
The LKH Multistage pump is designed for extremely high outlet pressures using multiple impellers, while the LKHPF is focused on high inlet pressure and filtration duties.

Q3: What is the LKH Evap pump used for?
The LKH Evap is an evaporator pump, engineered for evaporation processes requiring reliable handling under vacuum and high temperature conditions.

Q4: What is the LKHex pump?
The LKHex pump is a centrifugal pump designed for use in explosive environments, ensuring safe and reliable operation in ATEX-rated areas.

Q5: Is the LKHPF considered a vacuum pump?
While some queries mention “Alfa Laval vacuum pump,” the LKHPF is not a vacuum pump, it is a high pressure centrifugal pump. For vacuum applications, Alfa Laval provides different dedicated solutions.
