Alfa Laval SolidC UltraPure

The Alfa Laval SolidC UltraPure Centrifugal Pump has been designed to handle basic transport of fluids in high purity applications where contamination safety is of paramount importance. With its hygienic design, cost-effective operation and quick, easy maintenance, Alfa Laval’s SolidC UltraPure offers excellent value for money. The SolidC UltraPure comes with special features, inclusive of an external shaft seal and spring, a defined-compression O-ring in the back plate, crevice-free design and special standards-compliant materials throughout. The SolidC UltraPure is a standardized centrifugal pump for general applications, intermittent product pumping, and CIP duties. The SolidC Centrifugal Pump is also in compliance with 3-A, CE, FDA, and EHEDG requirements to ensure an excellent level of hygiene is provided.

Standardized and affordable 

Alfa Laval’s 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

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

Similar to Alfa Laval’s 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 

Alfa Laval’s SolidC UltraPrure 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 compromises 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 consists of a standard motor, stub shaft, mechanical compression coupling, stainless steel adaptor, back plate, impeller, pump casing and shaft seal.

Unique Impeller Design 

Alfa Laval’s 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 risks 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.

Semi-open impeller with balancing holes for high cleanability of the shaft seal.

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 the LKH UltraPure centrifugal pumps. This standardization keeps inventory down and makes replacing wearing parts a quick and easy task.

1. Defined O-ring groove providing firm positioning of the O-ring on pump casing and metal to metal contact provides a predefined compression of the O-rings with no crevices for contaminants.
2. External shaft seal with a few wear parts and spring mounted on the atmospheric side, meaning no wear of the spring or other internal parts going into your product.

Applications 

Alfa Laval’s SolidC centrifugal 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 used in the food, dairy, beverage, personal care, light chemical, and water industries.

Standard Design 

All media contacting steel components like pump casing, impeller, impeller nut and backplate are in W. 14404 (AISI 316L) with material traceability 3.1 according to EN 10204. A stainless steel shroud protects the motor and four adjustable stainless steel legs support the complete unit.

The semi-open impeller with a special vane design and balance holes enhance circulation around the shaft seal and reduce axial forces. This maximizes cleanability while minimizing wear on the shaft seal and motor bearings.

As standard the SolidC UltraPure pump is equipped with a single mechanical shaft seal, but also is available with a single flushed mechanical shaft seal. The secondary seal of the flushed seal is a long-lasting lip seal. The front-loading shaft seal, with the spring and washers mounted on the atmospheric side, make 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.
