BOYSER FMP-40 Peristaltic Hose Pumps

FMP-40 Model / 1 1/2”  BSP Connections


The FMP hose pumps are our largest peristaltic pumps fitted with roller technology, these units are equipped with reinforced hoses and rotors, heavily engineered integrated bearings, enlarged PU rollers as well as our patented clamping system. Thanks to its robust design and wide capacity range these peristaltic hose roller pumps are typically used in heavy duty industrial applications where the pump is a critical component in the process hence reliability is quite simply a must. Our hose pumps are available with integrated frequency drives, VFD rated drive units, certified ATEX, (explosion proof) motors and hydraulic motors.

The FMP series peristaltic pump, also known as a hose pump, is part of the positive displacement volumetric pump group. These pumps have quite a simplistic yet extremely robust design that enables them to be used for the most difficult of applications, such as transferring high viscosity products and fluids where a high concentration of solids is present, many of them being applications where other pumps would fail. Typical fluids include; Glue, Resins, Ink, Paint, Anti-foaming, Dyes, Detergents, Oils, Concrete, Mud, Sludge and Sewage/Effluent.


As one of their popular names indicates ‘hose pumps’, the pumping action is performed by a combination of a rubber hose located inside the casing of the pump and a rotor with a set of rollers or pads/shoes compressing the hose as they rotate. By pressing the hose whilst continually rotating, the rollers or pads push the fluid from the inlet side and towards the discharge side of the hose. This gentle pumping action means the flow rate achieved is directly proportional to the speed the rollers rotate and squeeze the tube/hose.


The unique pumping action creates a negative pressure on the suction side of the pump of up to 9 m.w.c., meaning the pump can self-prime and reach a suction lift of up to 9 metres vertically, this combined with the ability to run dry indefinitely and handle gasses makes the peristaltic hose pump the ideal solution for most pumping applications.


Another advantage of these pumps is how simple and economical they are to maintain. This is the due the fact that the hose is both the only wearing part in the pump and the only part that is in contact with the fluid.


The FMP range can be supplied either fixed speed or variable speed and is fully reversible. There are a wide range of accessories available to provide a complete custom solution for most applications, these are detailed below.

•    Pulsation Dampener – This is fitted downstream from the pump to ensure a smooth and stable flow. This is particularly beneficial when using ancillary equipment such as pressure switches and flow meters or when measuring the product for bottling, packaging etc.

•    Hose Leakage Sensor – This is connected to the pump casing and wired to an external control panel. The sensor detects if the internal rubber hose has broken and signals an alarm to warn the operator maintenance is required. This is particularly useful when the pump is unmanned, handling hazardous fluids or running continuously for critical applications.

•    Anti-corrosive Coating – The pump casing can be coated in Halar (ECTFE) for corrosion resistance. This is recommended when the pump is installed in a corrosive or hazardous environment.

•    Variable Speed Drive – The pump is supplied fixed speed as standard, an inverter can be fitted to the motor to enable variable flow rates, this is excellent for dosing and flow critical applications.

•    Air Operated Vacuum Pump – This is recommended for high suction lifts. The vacuum system ensures the hose does not collapse under extreme conditions and facilitates easier priming for the pump.

•    Screw Hopper Feeder – For dry and highly viscous fluids, a hopper/screw system is installed on the inlet side of the pump to enable easy flow of the product into the pump.

•    Mobile Trolley – The pump can be supplied on a mobile trolley for moving around site. Bespoke dimensions and materials are available on request.

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.

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.
