Pumps
The Alfa Laval range of pumps solves the entire range of tasks for gentle and precise pumping of liquids of any kind and any viscosity in systems with increased hygienic requirements.
Application
The SolidC pump is designed for pumping liquids for cleaning in place (CIP), water for heating, refrigeration and other process purposes, as well as washing machines and simply in pipeline systems within the operating range. SolidC is suitable for use in the food, dairy, pharmaceutical and light chemical industries, in the production of beverages and hygiene products, and in water supply networks.
Typical design
The SolidC pump consists of a standard motor, self-aligning shaft, mechanical compression coupling, adapter, backplate, impeller, shaft seals and housing.
Thanks to the large radii of curvature of the internal surfaces and the use of washable seals, the pump is suitable for cleaning in place (CIP).
The SolidC pump has a casing made of of stainless steel, covering the motor, and four height-adjustable stainless steel legs.
Shaft seals
The SolidC pump is equipped with an external single shaft seal (SSS) or a flushable shaft seal (FSS). Both types of seals consist of stationary sealing rings made of acid-resistant stainless steel AISI 329 with a silicon carbide sealing surface (SIC) and rotating sealing rings with a graphite surface (C). The secondary part of the flushable seal is a long life stuffing box.

They are capable of pumping media of various viscosities, from low to high, are suitable for cleaning in place (CIP) and meet the requirements of the US 3A standard for sanitary qualities. Due to the low shear force and smooth rotation of the rotors, these pumps are ideal for pumping products such as creams, gels, emulsions, aerated mixtures, as well as suspensions sensitive to mechanical stress of cells and organic particles. SRU pumps are compact and highly efficient. They develop a flow of up to 106 m3/hour and a pressure of up to 20 bar. New and improved modular design provides versatility, simplicity and low cost Maintenance.
Typical design Transmission The SRU is a traditional rotary pump design with a robust cast iron gearbox for maximum shaft stability and easy replacement of oil seals. Models SRU series 1 - 4 are equipped with a box with a universal housing design that allows installation with both vertical and horizontal connections, depending on the selected support. The SRU Series 5 and 6 models are equipped with a gearbox with a special housing design that also allows for both vertical and horizontal connections. The outside of the gearbox is coated with an anti-corrosion coating (epoxy paint).
The pump itself SRU pumps as standard have full bore inlet and outlet pipes that meet sanitary requirements and international standards, which guarantees low pressure losses and a high suction head of the pump. For pumping products with very high viscosity, the pumps can be equipped with extended pipes and connections rectangular section. The SRU pump has a three-cam rotor as standard. At the customer's request, the pump can be equipped with a two-cam rotor designed for pumping media with large particles that are sensitive to mechanical loads. Rotors are available that are designed for maximum temperature pumped product or cleaning liquid
