Service and Support For information with respect to specific adjustments, installation, maintenance or repair jobs which fall beyond the scope of this manual, contact your Bredel representative. Make sure you have the following data at hand: • Type and / or serial number of the hose pump.
Remarks, suggestions and advice. Intended Use and Remarks on Safety The bare shaft set is exclusively designed for supporting a Bredel or an APEX pumphead and a drive. Every other use is not in conformance with the intended...
GENERAL use. Refer to the manual of the pumphead for more information on safety and the intended use of the complete pump. Warranty Conditions Refer to the manual of the pumphead for warranty conditions. These conditions are applicable to the bare shaft set as well.
To align the pump and the drive use alignment jigs. The jigs are not included in the package. Although the instructions in this manual are demonstrated with the Bredel 10-20 pump series, these are also applicable to the APEX10-20 series.
Follow the unpacking instructions on the packaging. Check that your delivery is correct and does not have transport damage. Report any damage immediately to your Bredel representative. This chapter describes the installation of the bare shaft set. Refer to the manual of the pumphead for installation and setup of the complete pump and the pipework.
INSTALLATION 3.2.1 Mounting the support set and Bare Shaft Kit For mounting the kit to the pumphead, the pump must not be part of a process line and must be free of lubricant. Place the bare shaft kit (A) on a flat surface with the key end upward.
Page 11
INSTALLATION Remove the coupling guard from the support set. Use a hoist to place the support set on the rear of the pumphead. Place the bare shaft kit (A) with the 3-teeth coupling end into the pump. Make sure the 3 teeth correctly mesh with the holes in the rotor inside the pump.
INSTALLATION 3.2.2 Mounting and aligning the Drive Use a hoist to lift the drive. Mounting and aligning the drive must be done on the pump’s final operation position. Moving the complete pump assembly after alignment will require re- alignment at the pump’s final operation position.
Page 13
INSTALLATION Place coupling half (A) on the output shaft of the drive and slightly fasten screw (B). Make sure the shaft end has been shifted far enough into the coupling half but will not penetrate into the coupling spider (C). Use a hoist to place the drive on the support set.
Page 14
INSTALLATION Drive a pin (A) into each drilled hole to fix the horizontal plate in the support set side plates. Use two alignment jigs (D) to check the alignment of the coupling halves in the horizontal plane. Looking from above both coupling halves (C) must touch the edge of both jigs.
MAINTENANCE MAINTENANCE Cleaning WARNING When cleaning the pump do not use a high-pressure spraying pistol. This might damage the seal and the bearing. Demounting the Drive Use a hoist to lift the drive. Isolate the drive from the electrical supply. Loosen the fasteners (C) of the coupling guard and remove the coupling guard (B).
MAINTENANCE Demounting the Bare Shaft Kit When the bare shaft kit is demounted the pumphead will come loose from the support set. The pumphead must be supported in some way, or the pumphead has to be tipped to the front. In the latter case piping has to be disconnected and lubricant has to be removed first.
MAINTENANCE Disassembling the Bare Shaft Kit Remove coupling half (B) from the shaft by loosening screw (A). Use a suitable pulling device. Do not put axial load on the bearing if it is to be reused. Remove retaining ring (A). Remove key (B).
MAINTENANCE Remove bearing (B) from shaft (A). Use a suitable pulling device. Remove seal (A) from hub (B). If the seal is to be replaced pliers can be used. Assembling the Bare Shaft Kit Check the bearing and the seal before reuse. If necessary use a new bearing and a new seal.
Page 19
MAINTENANCE Use a suitable tool (A) to press seal (B) into the hub until it hits the collar. Keep the closed side of the seal upward. Put an excessive amount of grease on the lip of the seal. Clean the contact surfaces (A) for bearing and seal on the shaft (B).
MAINTENANCE Place key (B) onto the shaft. Place retaining ring (A) into the hub. Mount a coupling half on the shaft end. See section 3.2.1 step 1. Mounting the Bare Shaft Kit onto the Pump For this procedure the pumphead should still be placed on blocks with the support set resting on the pumphead´s rear side.
MAINTENANCE Mounting the Drive Use a hoist to place the drive on the support set. Make sure the spider (B) is placed in one of the coupling halves (A). Slide the drive toward the pumphead. Make sure the coupling halves (A) and the spider mesh correctly.
Page 22
MAINTENANCE Tighten the fasteners (B) to fix the drive to the support set with the correct torque. See section 6.3. Tighten the screws (A) in the coupling halves with the correct torque. See section 6.3. Place coupling guard (B). Place and tighten the fasteners (A) with the correct torque.
TROUBLESHOOTING TROUBLESHOOTING WARNING Disconnect and lock the power supply to the pump drive before any work is carried out. In case the motor is fitted with a frequency controller and has a single phase power supply, wait at least two minutes to make sure that the capacitors have discharged.
