Alfa Laval SolidC UltraPure Centrifugal pumps

Introduction

The Alfa Laval SolidC UltraPure Centrifugal Pump is 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.

Applications

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.

Benefits

• Low contamination risk: comes with 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:

material traceability, and pump supplied with Alfa Laval’s

Q-Doc package in line with Good Documentation

Practices (GDP).

Standard design

All media contacting steel components like pump casing,

impeller, impeller nut and backplate are in W. 1.4404 (AISI

316L) with material traceability 3.1 according to EN 10204.

Product wetted elastomers are specified to USP Class VI,

121°C Chapter 88. and Chapter 87. 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, makes 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.
