Adjustment of gland
Adjust the gland if the leakage rate is greater than or less than the specified rate.
Evenly adjust each of the two gland bolts with a one-quarter (1/4) turn until the desired leakage rate
is obtained. Tighten the bolts to decrease the rate. Loosen the bolts to increase the rate.
Tightening of packing
NOTICE:
Never over-tighten packing to the point where less than one drop per second is observed.
Over-tightening can cause excessive wear and power consumption during operation.
If you cannot tighten the packing to obtain less than the specified leakage rate, then replace the
packing.
6.4 Disassembly
6.4.1 Disassembly precautions
WARNING:
•
Failure to disconnect and lock out driver power may result in serious physical injury or
death. Always disconnect and lock out power to the driver before performing any in-
stallation or maintenance tasks.
•
Electrical connections must be made by certified electricians in compliance with
all international, national, state, and local rules.
•
Refer to driver/coupling/gear manufacturer's installation and operation manuals
(IOM) for specific instructions and recommendations.
•
Risk of serious personal injury. Applying heat to impellers, propellers, or their retaining
devices can cause trapped liquid to rapidly expand and result in a violent explosion.
This manual clearly identifies accepted methods for disassembling units. These meth-
ods must be adhered to. Never apply heat to aid in their removal unless explicitly stat-
ed in this manual.
•
Handling heavy equipment poses a crush hazard. Use caution during handling and
wear appropriate Personal Protective Equipment (PPE, such as steel-toed shoes,
gloves, etc.) at all times.
•
Precautions must be taken to prevent physical injury. The pump may handle hazard-
ous and/or toxic fluids. Proper personal protective equipment should be worn. Pum-
page must be handled and disposed of in conformance with applicable environmental
regulations.
•
Risk of serious physical injury or death from rapid depressurization. Ensure pump is
isolated from system and pressure is relieved before disassembling pump, removing
plugs, opening vent or drain valves, or disconnecting piping.
•
Risk of serious personal injury from exposure to hazardous or toxic liquids. A small
amount of liquid will be present in certain areas like the seal chamber upon disassem-
bly.
CAUTION:
•
Avoid injury. Worn pump components can have sharp edges. Wear appropriate
gloves while handling these parts.
