The Anko Mityflex® Peristaltic Pump, available in 907 and 908 series models, is a general-purpose fluid dispensing device designed for a variety of applications. These pumps operate on the principle of peristalsis, where fluid is moved through a tube by rollers compressing and relaxing the tube, creating a positive displacement flow. This design ensures that the fluid only contacts the inside of the tubing, preventing contamination of the pump mechanism and making it suitable for handling a wide range of liquids, including those that are corrosive or sensitive.
The primary function of the Anko Mityflex® pump is to accurately and reliably dispense fluids. Both the 907 and 908 models are fixed-speed pumps, meaning they operate at a constant rotational speed, resulting in a consistent flow rate for a given tubing size. The 907 model is a cased unit, featuring an integrated on/off switch and a power cord, making it a self-contained and ready-to-use device. In contrast, the 908 model is designed for OEM (Original Equipment Manufacturer) applications, supplied with a zinc-plated steel bracket and lead wires for easy integration into larger systems or custom setups.
A key characteristic of these peristaltic pumps is their self-priming capability. This means they can draw fluid into the tubing without external assistance, eliminating the need for manual priming. Furthermore, once the pump is turned off, it maintains a vacuum, preventing backflow and ensuring that the fluid column remains in place. The pumps are also designed to run dry without causing damage to the motor or drive unit, although continuous dry running may reduce the lifespan of the tubing. This feature provides an added layer of protection against operational errors or unexpected fluid supply interruptions.
The flow rate of the pump is directly dependent on the internal diameter (ID) of the tubing used. By selecting different tubing IDs, users can achieve a wide range of flow rates, from very low to relatively high volumes, making the pump versatile for various dispensing requirements. The pump head assembly, which houses the rollers and the tubing, is designed for efficient and consistent compression, ensuring accurate and repeatable fluid delivery.
The Anko Mityflex® pumps are engineered for straightforward operation and integration. For the 907 model, operation is as simple as connecting it to a power source and activating the on/off switch. Its cased design, complete with rubber feet and mounting flanges, allows for flexible placement on flat surfaces or wall mounting. Adequate air circulation is important for the 907 model, and its vent holes should not be obstructed. The 908 model, intended for OEM use, offers mounting brackets for secure integration into other equipment, emphasizing the need for sufficient air circulation around the pump to prevent overheating.
Proper installation is crucial for optimal performance. Users must ensure that the power supply voltage and frequency match the specifications of the unit. All wiring and electrical connections must adhere to local and national electrical codes to ensure safe operation. The mounting location should be dry and provide adequate cooling, with ambient temperatures not exceeding specified limits for AC and DC units. It is also critical to ensure that the tubing is not crimped during installation or operation, as this can impede flow and damage the tubing.
Tubing installation is a key aspect of using these peristaltic pumps. The manual outlines specific procedures (A, B, and C) tailored to different pump models and flow ranges, ensuring correct and secure placement of the tubing within the pump head. These procedures often involve carefully feeding the tubing into the roller race while the rollers turn slowly, or using an extra bracket to rotate the roller assembly for easier insertion. A warning is provided against rotating the drive shaft by hand for certain models, as this can cause damage. The pump's design includes grippers at the inlet and outlet ports to anchor the tubing, preventing it from slipping during operation.
The selection of appropriate tubing and rollers is vital for achieving desired flow rates and ensuring chemical compatibility. The manual provides guidance on color-coded rollers that correspond to specific tubing IDs, and users are advised to pretest tubing for chemical compatibility with the fluids being pumped. Tubing showing signs of deterioration, such as swelling or embrittlement, should be replaced immediately to maintain performance and prevent leaks.
Maintenance of the Anko Mityflex® pumps primarily revolves around the tubing and, for the 907 model, the fuse. Regular inspection of the tubing is recommended, and any signs of deterioration necessitate immediate replacement. This proactive approach helps prevent operational failures, fluid leaks, and potential damage to the pump or the surrounding environment. When working with chemicals, safety glasses and protective clothing are advised.
Replacing the tubing is a routine maintenance task, and the manual provides detailed, step-by-step instructions for each installation procedure. These instructions emphasize disconnecting power before maintenance, carefully removing the pump cover, and cleaning the roller race to remove any particles that could damage the new tubing.
For the 907 model, fuse replacement is a straightforward process. The fuse, located on the exterior of the case, protects the pump's electrical components. Instructions include disconnecting power, removing the case screws, carefully separating the case cover, locating and pulling apart the fuse holder, replacing the old fuse with a new one of the correct type, and reassembling the case.
Fan assembly and replacement are also covered, particularly for units that include a cooling fan. The fan is pressed onto the rotor shaft, and its orientation (metal clip away from the motor for 907 units, toward the door for 908 units) is specified. Disconnecting power is a prerequisite for any fan-related maintenance.
Roller replacement, while less frequent than tubing replacement, is also detailed. The manual describes how to remove the roller bracket assembly from the pump, disassemble it, replace individual rollers, and reassemble it, ensuring that the flats on the brackets align correctly. For plastic roller bracket assemblies, if new rollers are needed, a new assembly must be ordered, indicating that individual plastic rollers are not typically replaceable in these units.
The availability of replacement parts is crucial for long-term usability. The manual directs users to contact their local distributor for ordering parts and emphasizes including the complete model number to ensure correct part identification. A comprehensive list of replacement parts, including different roller bracket assemblies, pump kits, tube kits, and fuses (for the 907 model), is provided with corresponding unit numbers. This ensures that users can easily obtain the necessary components to keep their pumps in optimal working condition.
Overall, the Anko Mityflex® Peristaltic Pump is designed for reliable fluid dispensing with user-friendly operation and maintenance procedures, making it a practical choice for various industrial and OEM applications.
