0.1. Introduction The Tapflo Hose Pump range is a series of pumps for industrial and hygienic applications. The pumps are designed to be safe, simple and easy to use and maintain. The pumps are suitable for almost all different liquids used by the industry today.
The nameplate is made in the below design. It is made of AISI 304 stainless steel and placed on the pump stand or discharge flange bracket. Nameplate dimensions are 38 x 48 mm. PTL pumps PXTL pumps IOM manual Tapflo PTL Hose pumps...
1.1. Operation principle The Tapflo hose pump is driven by a gear-motor. The rotor is installed directly on the shaft and is equipped with rollers. The rollers compress the hose creating vacuum on the suction side of the pump and pressure on the discharge to transfer the liquid. The rotary movement of the rollers compresses the hose along the casing wall, constantly sucking/pushing the liquid through the hose.
(possibly eccentric on suction side and concentric on discharge side) at changes of diameter and at a minimum distance from pump connections of five diameters. IOM manual Tapflo PTL Hose pumps...
1.8.1. Protection In the interest of health and safety it is essential to wear protective clothing and safety goggles when operating, and/or working in the vicinity of Tapflo pumps. 1.8.2. Electrical safety Do not carry out any maintenance or/and operation on the pump while it is running or before it has been disconnected from the power supply.
1.8.3. Potentially explosive atmospheres – ATEX The standard PTL series pumps are not allowed to operate in potentially explosive atmospheres. Special PXTL pumps are available for such applications. Follow ATEX supplementary instructions (see section 7) and local/national rules for safe use.
Even if all above safety instructions are met and complied with, there still exists a minor danger in the event of a leakage or mechanical damage of the pump. In such case the pumped product can emerge on sealing areas and connections. IOM manual Tapflo PTL Hose pumps...
1.12. Gear-motor standard As a standard Tapflo Hose pump are equipped with gear-motors of the following parameters: ➢ International Mounting Arrangement – B5 ➢ Number of poles / Rotation speed [rpm] – 4 / 1400 ➢...
The performance of the pump can be adjusted by means of a frequency inverter. The flow depends on direction of rotation and can achieve full capacity in both directions of rotation. IOM manual Tapflo PTL Hose pumps...
Even with proper application and observance of all points listed in this operating manual, there is still an estimable and unexpected residual risk when using the pumps. It may leak, fail due to wear, application-related causes or system-related circumstances. IOM manual Tapflo PTL Hose pumps...
When fluid leakage occurs, the power supply has to be closed and the pressure released. During spillage of an aggressive liquid, local and national safety rules must be followed. IOM manual Tapflo PTL Hose pumps...
In case any of the above is not fulfilled, do not start the pump and implement corrective actions. Establish a preventive maintenance schedule based on the pump’s service history. Scheduled maintenance is especially important to prevent spills or leakage due to hose failure. IOM manual Tapflo PTL Hose pumps...
The characteristics of the liquid, temperature, materials used in the pump and running time decide how often a complete inspection is necessary. Nevertheless, Tapflo recommends to inspect the pump at least once a year. If a problem has occurred, or if the pump is in need of a complete inspection, refer to chapters 3.5 "Location of faults"...

ATEX supplementary manual 7.1. Potentially explosive atmospheres - ATEX The standard PTL series pumps are not allowed to operate in potentially explosive atmosphere. Special PXTL pumps are available for such applications. Follow this ATEX supplementary instructions and local/national rules for safe use.
EN 60079-19 standard. 7.6. Spares ➢ Only original Tapflo spare parts can be used for spare parts replacement. Failing to follow the instruction voids the ATEX marking. ➢ When ordering spares ATEX execution must be clearly mentioned. Always indicate pump code and serial number.
Even if there is no source of ignition, it is essential to stop the pump as soon as possible. For that purpose all Tapflo ATEX rated pumps are equipped with a leak sensor. The sensor must be connected to a circuit (e.g. via frequency inverter) that automatically stops the pump.
