DESCRIPTION

BOYSER DS-M Peristaltic Dosing Pumps


The DS-M pumps are our smallest peristaltic pump series, these hose pumps are very common within the Chemical and Food industry, typically used for dosing or simply transferring small amounts of products at low pressure, they have a quite compact design whilst still being very powerful as they can reach a discharge head of 20 metres. These pumps have 6 different tube diameters which can be interchangeable between the 18 pump sizes/configurations available. All pumps are fitted with a triple rotor containing three rollers as standard this design feature makes the DS-M range highly accurate whilst it minimises flow pulsations.

 

Typical Applications/Industries:

 

Chemical Dosing.

Water Treatment.

Food/Beverage Transfer.

Sampling.

Paper Industry.

Pharmaceutical.

Paper Industry.

FAQS

Yes, absolutely! Due to their unique design, peristaltic pumps can run dry indefinitely. As there is no mechanical seal that requires lubrication and the only pumping component is a rubber hose, the pump can run without fluid for long periods without risk of damage to the internal components or motor.
A pump must be primed in order to operate correctly, this means that the pump casing and inlet pipe must be filled with fluid and the air removed before operation. This needs to be done manually by the pump operator for a non-self-priming pump each time the pump is used to avoid damage from dry running. A self-priming pump removes these issues by completing the priming process automatically. The air is removed from the inlet pipework and pump casing when the pump is activated. Self-priming pumps are particularly useful for installations with a suction lift on the inlet side of the pump, the pump will draw the fluid up the pipework by creating a vacuum and removing any air that is present. In ideal conditions, a self-priming pump can lift fluids up to around 9m on the inlet side, however this figure is affected by fluid viscosity, pipework bore and other installation conditions, therefore this figure can be much lower from case to case. Allowances must also be made for wear and tear; suction lift capabilities will be much lower for older and worn pumps.
Please be aware that the figures displayed relate to the largest pump from this range of products, not specific models. A typical rule of thumb with peristaltic pumps is that the maximum solids size is equal to the internal diameter of the hose. For details on solids passage for specific models, please refer to datasheets or contact a member of our sales team.
Please be aware that the figures displayed relate to the largest pump from this range of products, not specific models. For details on viscosity for specific models, please refer to datasheets or contact a member of our sales team.
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, viscosity, size and type of solids, 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. Viscosity is a major factor when selecting the correct motor speed. A full speed pump will not transfer high viscosity fluid correctly, whereas a slower speed pump will have a much gentler pumping action. 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 slower speed motor rather than a full speed 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.
Firstly, always check the compatibility of the materials available against the fluid being pumped. The main materials to check are the connections and the hose. It may be that more than one material is suitable for your fluid and selection could be based on the application type. For instance; NR, NBR, EPDM, NBR-A, HYPALON, NORPRENE are all suitable for water. If it is a simple transfer application, then the most cost-effective material will be best. However, if it involves abrasive solids or there is another variable to consider, then an alternative material may be a better selection.
Rollers and shoes are the rotating components in peristaltic pumps, they are two different designs for different application types. Although different, both operate in a very similar manner. The shoes/rollers are connected to a shaft from the motor/gearbox, these rotate at a low speed and squeeze the hose inside the pump to force the fluid round.

The roller design has the main benefit that far less lubrication is required for the hose, however the pump is limited to a maximum pressure of 8 bar.

Other benefits of the roller design include;
• Longer hose lifespan, energy savings up to 30% compared to a shoe pump design.
• Easier maintenance (there is no need to drain lubricant from the pump and then to refill again, less mess).
• Any product leakage is 100% recoverable from the drainage port (lubricant from a shoe pump can mix with the leaked product and is then not recoverable).

The shoe design requires the hose to be submerged in large quantities of lubricant, however the pump can achieve pressures up to 15 bar.

Both designs are available with the same types of inlet/outlet connections and accessories such as variable speed drive and leakage sensor. The best solution for you is entirely dependent on the application, fluid and flow rate/pressure requirements.
This depends entirely on the application and can vary case by case. The life of the hose is affected mainly by the abrasiveness of the product being pumped, the pump speed (RPM) and how many hours a day the pump is operating. Hose life can be optimized by making the correct pump selection at the beginning of the process. For example, we recommend installing a larger pump running at a very low RPM if the fluid is abrasive and the pump is running 24 hours a day. By using a larger pump at a slower speed, the hose will wear far less, and the life will be extended significantly.
