Our sanitary centrifugal pump range has been specifically designed for the pharmaceutical, cosmetic, food and beverage industries, these pumps are FDA and EHEDG approve which means both the material of construction and the design of the pumps comply with the highest European hygienic standards and regulations. Due to their fully hygienic inner construction these centrifugal food-grade pumps can be clean by either CIP (clean in place) or SIP (sterilization in place) processes therefore no disassembly is required in order to clean the internal components of the pump consequently making its day to day maintenance and operation extremely simple as well as reducing downtime considerably.

Besides being fully sanitary pumps, these range of centrifugal pumps are highly efficient as they require a lower power consumption than other hygienic centrifugal pumps, the impeller used within these pumps is also highly efficient and as a result the NPSH required for this range is also lower than usual thus reducing considerably the risk of cavitation. These pumps are available with a wide variety of hygienic connections or fittings such as DIN 11851, DIN 11861, RJT, SMS, TRI-CLAMP, etc.

North Ridge Sanitary Centrifugal Pumps are also available with ATEX (explosion proof) motors typically used in non-safe (hazardous/explosive) atmospheres and for transferring highly flammable liquids such as ethanol, butanol, methanol and any alcoholic spirits, there are also a variety of accessories and additional features available upon request, some of the most popular are double mechanical seal with thermosyphon cooling, heating chamber on pump body, VFD (frequency drive), trolley mounted etc.

FAQS

What does the term CIP mean?

Clean In Place (CIP) is a term used in the food, beverage and pharmaceutical industries. It is a process of cleaning the internal surfaces of vessels, filters, pumps, pipework and fittings without having the disassemble any components. A high temperature cleaning fluid is typically pumped through the components for a certain amount of time until they are clean and ready for use.

Can this pump run dry?

No, definitely not! Centrifugal pumps will incur damage even after short periods of dry running. The mechanical seal will be destroyed, and this will cause the pump to leak. There is also the possibility that the motor will burn out. Our advice is to ensure that the pump has a flooded suction or always make sure that the pump casing and inlet pipe are filled with water; one way of ensuring this is to fit a check valve on the inlet line to stop water escaping when the pump is inactive. Another way of protecting the pump is to fit a dry running device, this will turn the pump off if it detects that that no fluid is entering the pump. If you think that dry running is inevitable, then please speak to us and we will try to select a more suitable pump for your application.

How do I know what size pump and motor speed is correct for my application?

A clear picture of the pump system is required to make an accurate selection. The main pieces of information required include; a description of the application, bore of pipework, the fluid, flow rate and pressure/head. With these pieces of information, a pump can be sized correctly to ensure it delivers the required flow rate and pressure and that is also operates at its best efficiency point to lower lifetime costs. Knowing if the pump is running intermittently or continuously also allows the correct motor speed to be selected. For instance, a pump running continuously 24/7 will require a 4 pole motor rather than a 2 pole motor. Running the motor slower and oversizing the pump will reduce wear of the motor and the pump, therefore lowering maintenance costs during their lifetime.

What food grade standards does this pump adhere to?

Please note that the standards vary by model. Our centrifugal food grade pumps comply with standards EHEDG and 3A for use in the food, beverage, chemical, cosmetic and pharmaceutical industries. These series are designed for maximum sterilisation when performing clean in place (CIP).

What food grade connections are available with this pump?

Our food grade centrifugal pumps are available with various connections, including; DIN 11851, Clamp ISO 2852, Clamp ASME-3A, Clamp DIN 32676, RJT and SMS 1145.

The food product I am pumping is shear sensitive and viscous, are there more gentle food grade pumps available?

If the food or beverage product you are pumping is highly viscous, contains solids or is shear sensitive, then a more specialist pump such as a peristaltic, flexible impeller or progressive cavity pump may be a better solution. Please contact a member of our sales team and we will try our best to assist you.

What do the terms Atex and explosion proof mean and why are they so important?

ATEX is an abbreviation of “Atmospheres Explosibles”. It is a regulation set out by the European Union to ensure the safety of products that are used to handle flammable products or are installed in environments containing flammable gases, vapours, mists or combustible dusts. For instance, if the pump is being installed in an explosive environment, then only the motor needs to meet the Atex standard stopping it from causing a spark during operation and igniting the atmosphere. However, if the fluid being pumped is flammable, then the pump will also need to meet Atex standards to ensure that no sparks are caused inside the pump itself when the fluid goes through it. It is crucial that an Atex rated pump or motor are used for applications involving explosive environments or flammable fluids, using a non-Atex pump or motor in these situations is extremely dangerous and contravenes health and safety standards.

What is NPSH and why is it so important?

NPSH is an acronym for Net Positive Suction Head. NPSH measures the absolute pressure present in a fluid.

There are two main ways that NPSH is expressed in a pump system

NPSHa - This is the amount of Net Positive Suction Head available at the pump inlet. NPSHa demonstrates the amount of pressure acting on a fluid as it enters the pump. This measures the amount of pressure between the liquid staying in its current state and forming vapour bubbles (beginning to boil).

NPSHr - This is the amount of Net Positive Suction Head that the pump requires to operate without experiencing the damaging effect of cavitation, thus causing a dramatic reduction in pump performance.

It is very important to pay attention to these values when making a pump selection. Selecting a pump that requires more NPSH than is available in your system will cause fast and long-lasting damage to the pump and thus you will incur large repair costs and downtime.

What does the term best efficiency point (BEP) mean and why is it so important?

The best efficiency point or BEP is a point along the pump performance curve that indicates where efficiency for the pump peaks. When selecting a pump, you must try and get as close to the BEP as possible to ensure that the pump is at maximum efficiency when operating. The closer to the BEP the pump is when operating, the lower the energy costs will be, thus saving significant amounts of money during the pump’s lifetime. Also, vibrations will be at their lowest meaning maintenance costs are lower and the lifespan of the pump is maximised. It is very important to pay attention to the BEP when your pump is selected, as an oversized or undersized pump could cost you significant amounts of money.
