The special features of SolidC UltraPure centrifugal pumps include an external shaft seal and spring, a defined-compression O-ring on the back plate, crevice-free design and special standards-compliant materials throughout.

Designed to meet the hygienic requirements of the food, dairy, beverage, personal care, pharmaceutical, light chemical, and water industries, the SolidC pump series combines efficiency with competitive pricing. SolidC is a standardized centrifugal pump for general applications, intermittent product pumping, and CIP duties. Compliance with 3-A, CE, FDA and EHEDG requirements provides an excellent level of hygiene.

Standardized and affordable

The SolidC UltraPure is a standardized centrifugal pump design that is ideal for use in duties such as Cleaning In Place (CIP) and intermittent product pumping. It is the prime choice for installations where the combination of hygiene and purchase price is the key criterion.

Easy to keep clean

SolidC UltraPure centrifugal pumps are designed with features that ensure consistent performance as well as eliminating any risk of contamination. In-depth process knowledge has resulted in a design that avoids any crevices in which contamination might accumulate or bacterial growth can build up. This makes the SolidC quick and easy to clean, saving time, cleaning agents and consumption of high-purity water.

Just like the premium LKH UltraPure, the SolidC UltraPure features an external shaft seal and a semi-open impeller with balance holes. Together with a crevice-free design, these are three key features in ensuring end-product quality.

Supply and delivery

SolidC UltraPure units are available in four different sizes. All standard components are kept in stock to shorten lead times and to avoid any unnecessary downtime.

Biopharm documentation package

All Alfa Laval biopharm components are delivered with Q-doc product documentation based upon GDP (good documentation practice). The Q-doc package comprises equipment manuals, factory acceptance tests/performance test, quality and manufacturing procedures, relevant material certificates and the necessary parts and service information.

Warranty

Alfa Laval provides a 3-year warranty on all non-wearing parts, provided genuine parts are used.

SolidC UltraPure construction

The pump consist of a standard motor, stub shaft, mechanical compression coupling, stainless steel adaptor, back plate, impeller, pump casing and shaft seal.

Unique impeller design

SolidC UltraPure centrifugal pumps feature a unique semi-open impeller with a special vane design that ensures  particularly low NPSHr (Net Positive Suction Head required), which is the total pressure at the suction nozzle necessary for the pump to operate properly. This helps prevent cavitation effects, and minimizes any risk of mechanical damage.

The impeller also features balancing holes that provide excellent circulation in the shaft seal area as well as reducing axial forces on the impeller. This reduces wear on both the shaft seal and the bearings of the drive motor.

External shaft seal

The front-loaded external shaft seal, with the spring and washers mounted on the atmospheric side, is an important feature of the SolidC UltraPure design. This configuration makes maintenance rapid, easy and inexpensive – it only takes about 5 minutes to replace the shaft seal.

Using a front-loaded shaft seal, combined with the pipe couplings mounted on the pump housing, also means there is no need to disconnect or remove the pump casing for inspection or maintenance. This saves time and money, and helps keep downtime to a bare minimum. This feature also means that a spare pump without casing could also be quickly put into place .

Alfa Laval uses the same shaft seal for the whole SolidC UltraPure range – and the same seal is used in LKH UltraPure centrifugal pumps. This standardization keeps inventory down and makes replacing wearing parts a quick and easy task.

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.
