Solid value
The SolidC centrifugal pump is a standard duty pump for basic transport duties in hygienic applications. An exceptional value compared with other pumps in its class, it provides reliable, low-maintenance operation. With its hygienic design, cost-effective operation and quick, easy maintenance, the SolidC offers excellent value for money.
For more demanding duties, Alfa Laval offers the premium LKH centrifugal pump. Using our pump selection software, Alfa Laval or one of our sales and working partners can help you select the right pump for your specific application.
Solid hygienic design
SolidC centrifugal pumps ensure consistent performance and maximum cleanability. The pump interior is designed to provide control of surface contamination and feature O-rings with defined compression. Compliance with 3A, CE, FDA and EHEDG requirements provide an excellent level of hygiene.
Engineered for high product integrity, the SolidC has a semi-open impeller, which provides gentle product handling. Smooth crevice-free surfaces eliminate any dead zones where bacteria can thrive. In addition, the SolidC is easy to clean in place and employs FDA-approved elastomers.
Easy, low-cost maintenance
A few minutes are all that is required to change wear parts. Hassle-free replacement of the easy-to-access front-loading shaft seal, for instance, maximizes uptime and minimizes maintenance costs. Other features that contribute to solid maintenance routines and cost savings are the easy-to-disassemble clamp between casing and back plate and easy-to-mount O-ring.
Warranty
Alfa Laval provides a three-year warranty for all non-wearing parts, provided genuine parts are used.
Applications
The SolidC pump is designed for standard duty applications: pumping CIP (Cleaning In Place) solutions, utilities, water (processing, heating, cooling), washing machines, and simple transport duty within working range. SolidC is suited for use in the food, dairy, beverage, personal care, light chemical, and water industries.
Standard Design
The SolidC pump consists of a standard motor, stub shaft, mechanical compression coupling, adaptor, backplate, impeller, pump casing, and shaft seal. The SolidC pump is designed for CIP with emphasis on large internal radii and cleanable seals. The complete SolidC unit is supported on four adjustable legs.
Shaft Seals
The SolidC pump is equipped with either an external single or a flushed shaft seal. Both have stationary seal rings in acid-resistant AISI 329 steel with sealing surface in silicon carbide and rotating seal rings in carbon. The optional flush seal has a long-lasting lip seal.

Pump range
SolidC centrifugal pumps are available in four different models that are capable of handling flow rates up to 90 m3/h, pressure heads up to 80 meters (8 bar) and inlet pressures up to 40 meters (4 bar).
Unique impeller design
The semi-open impeller with a special multi-vane design ensures particularly low NPSHr (Net Positive Suction Head required). This helps prevent cavitation and minimizes the risk of pump damage.
The impeller also features balancing holes that enhance circulation around the shaft seal and reduce axial forces. This maximizes cleanability while minimizing wear on the shaft seal and motor bearings.

External shaft seal
SolidC pumps use the same external mechanical shaft seal as the Alfa Laval LKH premium range of centrifugal pumps. This reduces spare parts inventory for plants that use both standard and premium Alfa Laval centrifugal pumps.
The front-loading shaft seal, with the spring and washers mounted on the atmospheric side, is an important feature of the SolidC design. This configuration makes maintenance fast, easy and inexpensive. It takes just a few minutes to replace the shaft seal.
One-piece pump housing
The pump housing is made of a sturdy single piece of stainless steel. There is therefore no need to disconnect or remove the pump casing from the process line during inspection or maintenance. This feature, combined with a front-loading seal, helps keep downtime to a minimum and saves time and money. This also means that, if required, a spare pump without casing can quickly be put into place.
Optimised shaft seal
One shaft seal fits a wide pump range. All models of the SolidC pump and 11 models of the LKH pumps share the exact same single shaft seal. 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.
