Manual No/Rev W77-009E / 2 Operators Instructions for XF300 & XF400 Range Centrifugal Pumps INTRODUCTION This manual gives the safety, installation, operation and maintenance instructions for pumps in the SPP Pumps’ AUTOPRIME XF range of horizontal, end suction, centrifugal pumps for vacuum assisted self priming applications. Instructions and statements contained within this handbook are given with our best intentions and are correct at the time of compilation. They are subject to alteration at any time.
Operators Instructions for XF300 & XF400 Range Centrifugal Pumps This symbol gives warning of a hazard to the pump itself, which in turn could cause a risk to personal safety. 2. TRANSPORT HANDLING & STORAGE INSTRUCTIONS 2.1 Transport cast iron parts, and should not be removed until final installation. 2.3.2 Fill the seal and bearing housings with recommended oil to ensure that the shaft, seal and bearings remain rust free.
Manual No/Rev W77-009E / 2 Operators Instructions for XF300 & XF400 Range Centrifugal Pumps The discharge branch is positioned at 45° above the centre of the pump volute. This allows the fitting of a ball or flap type nonreturn valve to give a horizontal discharge. The pump is centreline mounted and the volute is provided with an access point for examination of the impeller. The pump has been designed for use with an automatic priming system typically one using a vacuum pump with a priming tank.
Operators Instructions for XF300 & XF400 Range Centrifugal Pumps 4.4 4.5 a) Lateral Alignment Mount a dial gauge on the motor shaft or coupling with the gauge running on the outer machined diameter of the pump coupling. Turn the motor shaft and note the total indicator reading. b) Angular Alignment Mount a dial gauge on the motor shaft or coupling to run on a face of the pump coupling as near the outside diameter as possible. Turn the motor shaft and note the total indicator reading.
Manual No/Rev W77-009E / 2 Operators Instructions for XF300 & XF400 Range Centrifugal Pumps clean to ensure that site debris is not drawn into the pump when it is commissioned. 4.7 4.9 The pump is designed to be secured to a substantial baseplate to maintain the shaft alignment between the driver and the pump. The baseplate should be securely located on level ground or mounted on foundations. The shaft alignment should be checked again before commissioning and putting the pump into operation.
Operators Instructions for XF300 & XF400 Range Centrifugal Pumps Mechanical Seal Oil Filler Plug Manual No/Rev W77-009E / 2 head requirements. Bearing Oil Filler/Breather If the pump is operating at its normal speed, the pump should be shut down at once if any of the following defects are found: Mechanical Seal Oil Level Sight Glass Bearing Oil Running Level Sight Glass a) b) c) d) Recommended corrective action for these faults is given in Section 7 Faults and Remedial Action.
Manual No/Rev W77-009E / 2 Operators Instructions for XF300 & XF400 Range Centrifugal Pumps contaminated replace the mechanical seal. b) Bearing Temperature Check the outer bearing housing temperature does not exceed 80degC. c) Bearing Lubrication Check that the oil level is visible in the running level sight glass and look for evidence of contamination. Top up with 0.1 litres of oil if required, check level again when pump has run for 5 minutes, top up with 0.
Operators Instructions for XF300 & XF400 Range Centrifugal Pumps maintenance area. Recommended Maintenance Schedule PERIOD It is important to ensure the suitable lifting equipment is available and that the work is carried out in a clean area. TASK Check the bearing lubricating oil level in the bearing housing running sight glass and top up oil if needed with 0.1 litres of oil. Check the mechanical seal lubrication oil level and top up if required.
Manual No/Rev W77-009E / 2 d) Operators Instructions for XF300 & XF400 Range Centrifugal Pumps Initial Lubrication: Oil chambers on these pumps are emptied for transport and must be filled with the specified oil to the required level prior to running. After the first 50 hours of operation, drain off a sample and check for any oil contamination. If any contamination is found, the oil is to be changed. 6.5 i) Wipe the seal recess clean, lubricate the ‘O’ ring with a light smear of seal lubricating oil.

The run-out should not exceed 0.05 mm in any of the positions measured.
Operators Instructions for XF300 & XF400 Range Centrifugal Pumps tighten the capscrew to 350 Nm. Fit the cover plate A100 and if removed, insert oil level sight glasses A230, drain plug A140 and overflow plug A180. Fill the housing with bearing oil to the correct level. e) Rotate the impeller and visually confirm that it runs true, if not remove, clean all parts and reassemble. Back Wear Plate Assembly Clean the ‘O’ ring grooves lubricate and place the ‘O’ ring D40 into the groove.
Manual No/Rev W77-009E / 2 Operators Instructions for XF300 & XF400 Range Centrifugal Pumps 7. FAULT FINDING & REMEDIAL ACTION 7.1 Priming System Faults Pump Fails to Prime Check pump drain valve is closed. Check vacuum pump is operating, if not rectify or replace the pump. Disconnect vacuum hose and take a vacuum reading, refit the hose and fit vacuum gauge to the pump inlet and take another vacuum reading. Are vacuum gauge readings the same? YES Check the suction hose for internal collapse.
Operators Instructions for XF300 & XF400 Range Centrifugal Pumps 7.2 Manual No/Rev W77-009E / 2 Pump Fault Finding POTENTIAL FAULT OR DEFECT: Insufficient liquid delivered. Liquid delivered at low pressure (Fails to achieve the required delivery head) Loss of liquid after starting. Excessive vibration. Pump bearings run hotter than normal. PROBABLE CAUSES Speed too low. Speed too high.
