Solid value for money – consistent performance, excellent hygiene and maximum cleanability

  • Low process contamination risk – compliance with global hygienic design standards and verified cleanability
  • More uptime due to quick and easy maintenance
  • Continuous operation – no unplanned production stops due to robust mechanical design and front-loading shaft seal
  • Peace of mind thanks to an extended three-year warranty

The SolidC is a reliable, cost-effective centrifugal pump that delivers consistent performance in hygienic applications.

Its semi-open impeller, external front-loading shaft seal, single-piece stainless steel housing, and long-life compression couplings contribute to solid performance, high product quality, and ease of maintenance.

This standard centrifugal pump is available in four models capable of handling flow rates up to 80 m3/h, pressures up to 8 bar at 50 Hz, and inlet pressures up to 4 bar.

Solid hygienic design

Minimize contamination risks through compliance with 3-A Sanitary Standards, CE, FDA and EHEDG requirements.

Gentle product handling

The semi-open impeller of the SolidC ensures gentle product handling and high product integrity.

Easy, low-cost maintenance

With the spring and washers mounted on the atmospheric side, the front-loading shaft seal ensures quick, easy and cost-effective

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.

How it works

Operating principle

The pump impeller of the Alfa Laval SolidC centrifugal pump is mounted on a shaft, driven by an electric motor. The shaft turns and transfers the rotational energy to the fluid passing through the pump. The centrifugal force of the fluid increases the fluid’s kinetic energy and velocity as well as the pressure in the pump. The centrifugal force then directs the fluid towards the pump outlet.

Pump range 

Four different SolidC models handle flow rates up to 80 m3/h, pressures up to 8 bar at 50 Hz, and inlet pressures up to 4 bar.

Unique impeller design

The semi-open impeller with a unique multi-vane design ensures particularly low NPSHr (Net Positive Suction Head required), which helps prevent cavitation and minimizes the risk of mechanical damage. Impeller balancing holes enhance circulation around the shaft seal and reduce axial forces. This maximizes cleanability and minimizes wear on the shaft seal and motor bearings.

One-piece pump housing

The pump housing is constructed from a sturdy, single piece of stainless steel. There is 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, minimizes downtime and saves time and money.

Optimized shaft seal

One shaft seal fits all models of SolidC and LKH pumps. This standardization reduces inventory and makes wear parts replacement quick and easy.

Compression coupling

The compression coupling attaches the stub shaft to the motor shaft with precision alignment. Setup is simple, operations secure and noise, vibration minimized, and the service life of the shaft seal and motor prolonged.
