The Alfa Laval SolidC UltraPure Centrifugal Pump is part of a trusted range of high purity pumps designed for 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, the SolidC UltraPure offers excellent value for money.
Solid value for money – consistent performance, excellent hygiene and maximum cleanability
- Low contamination risk: full material traceability and USP Class VI elastomers to reduce the risk of process contamination from extractables.
- Cost-effective operation: consistent performance ensured.
- Quick and easy maintenance: wear parts changed in just a few minutes.
- Smooth qualification, validation and process control
The Alfa Laval SolidC UltraPure pump is designed to meet the stringent demands and regulations of high-purity applications across the biotechnology and pharmaceutical industries, which require equipment with the highest material integrity. All pumps are delivered with a complete Alfa Laval Q-doc package for easier validation and provide proof of origin and compliance for inspection purposes according to Good Manufacturing Practice (GMP) and ASME BPE requirements. The SolidC UltraPure pump is available in four sizes to handle capacities up to 75 m3 /h and differential pressures up to 8 bar at 50Hz.
How does the Solid C UltraPure works
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.
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 LKH UltraPure centrifugal pumps. This standardization keeps inventory down and makes replacing wearing parts a quick and easy task.
: 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.

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