SELF PRIMING CHEMICAL
SERVICE PUMPS
INSTALLATION AND OPERATING INSTRUCTIONS
This Manual covers:
SELF PRIMING MODEL RANGE
J50ECX TO J250ECX
STAINLESS STEEL*, and NON METALLIC SEAL
IMPORTANT
ALL ELECTRICAL WORK SHOULD ONLY BE
UNDERTAKEN BY QUALIFIED ELECTRICIANS
WARNING
Before disconnecting electrical connections ensure that electricity supply is switched off and
isolated at source.
If pump has been taken out of service, ensure that the drain plug is replaced and the sealing
washer is in good condition and the unit is primed for initial start-up.
Use only BRAUDE spares available ex-stock from:
E. BRAUDE (LONDON) LIMITED.
NOTE:
NEVER WORK ON THE PUMP WITHOUT FIRST MAKING CERTAIN THAT
POWER SUPPLY IS SWITCHED OFF AND ISOLATED AT SOURCE

I. LOCATION, FIXED DUTY
Locate the pump as close as possible to the liquid to be transferred. Provide the
necessary space around the pump for inspection and servicing. If possible, allow
several inches of clearance below the pump and motor to allow easy access to the
bottom seal plate-to-tank fixing cap screws. These cap screws must be removed for
servicing.
The pump should be mounted on a fixed and firm base by means of bolts. The ambient
temperature of the location should not exceed 40C.
II. INSTALLATION
Connect the pump using suitable polymer pipe. The pump suction line should not be
smaller than 63mm OD (2” NB). It is recommended for optimum operation that the
discharge pipe is also 63mm OD. All piping must be air tight; especially that of the
suction line.
Your pump is made of some of the finest engineering materials available today. A few
simple precautions, taken during the initial installation, will insure many long years of
trouble-free operation.
The pipe should be connected to the pump using suitable union rings with a 2¾” BSP
thread.
CAUTION
Tighten the pump fittings by hand only as much as is required to ensure a
tight connection. Excessive torque is unnecessary and may cause damage
to the pump – we do not recommend the use of a strap wrench or similar.
The weight of the pipe work should be supported independently and not
carried by the pump.
The pump motor must be wired for the proper voltage and rotation, in accordance with
the wiring diagram supplied with the motor, packed inside the terminal box. All wiring
should be carried out by a licensed electrician in accordance with local codes. Ensure
that the motor frame is grounded. The supply voltage, phase, full line current and
frequency are given on the motor rating label.
III ROTATION
Your pump is specifically designed to rotate in a counter-clockwise direction when
viewing the motor from the pump end. Please see direction of arrow on the label fixed
to the fan cover. Three-phase motors can rotate in either direction. Interchanging any

Page 3 of 11
IN0021 Rev11 Dec 2020
two leads of a three-phase motor will reverse the rotation. Momentarily start or "bump"
the motor to check the rotation of the pump shaft.
This test has be to carried out without liquid in the pump, otherwise the impeller
can be seriously damaged
IV. PRIMING
Fill the pump tank with water or the process liquid to be pumped. This may be done by
removing the strainer cover lid. When replacing this cover, caution should be taken to
avoid tightening more than "hand tight" (The pump lid may be secured firmly using the
tool supplied, taking care not to over tighten). BRAUDE Pumps prime themselves
providing the pump tank is filled with liquid.
V. OPERATION
Should you lose the priming or process liquid accidentally or by draining purposely, it
will be necessary to refill it with liquid before starting. High suction lifts, or long suction
lines, require additional time and reduce the performance of the pump. Should you have
difficulty, refer to the "Problem Solving Guide".
The latest engineering advancements have been incorporated into our self-lubricating
shaft seal. The liquid being pumped cools and lubricates the seal. Running the pump
dry will damage the seal. Always keep liquid in the pump tank. No further lubrication of
the pump end is necessary.
After the pump has been filled with liquid, and the motor started, allow a few moments
for the pump to start delivering liquid. If flow does not start within five minutes, stop
motor and determine cause (see Problem Solving Guide). Be sure all suction and
discharge valves are open when the pump is running. Operating the pump with a closed
valve in the system can cause pump damage.
VI. MAINTENANCE
The strainer built into the pump should be inspected and cleaned at regular intervals.
The strainer is easy to clean, remove the strainer cover lid to expose the strainer basket.
Remove and clean. Inspect the cover gasket 'O' ring, if damaged, replace. Replace
cover lid, “hand tight”. (The pump lid may be secured firmly using the tool supplied,
taking care not to over tighten).
When not in use if the pump is installed outside or in a position where temperatures will
drop to below freezing point, the pump should be completely drained of all liquid by
removing the drain plug, it can be stored in a strainer basket. In severe conditions and

Page 4 of 11
IN0021 Rev11 Dec 2020
periods of non use, the motor and impeller assembly can be removed and stored if
preferred.
IMPORTANT - The Impeller on this pump should always be secured to the motor
shaft using a suitable adhesive such as Loctite 499, or similar.
When activating the pump again, reverse the above procedure. Replace the gasket
between the tank and seal plate if damaged. Install drain plug. Check the pump shaft
for free movement. Prime the pump as above and check the rotation of the pump shaft.

PROBLEM SOLVING GUIDE
SYMPTOM I - PUMP WILL NOT PRIME
PROBABLE CAUSES AND RECOMMENDED ACTION:
a. Suction Air Leak
Check that liquid is available to suction line, suction hose/pipe and
connections are in good order, no air leaks. Check strainer basket is clean
and unobstructed, ‘O’ ring gasket is in good condition, replace and tighten
cover lid. Remove and inspect pump seal, replace if suspect.
b. No Liquid in Pump
Make sure pump tank is primed if new or full of liquid if used before.
c. Closed Valves or Blocked Lines
Open all valves between pump and liquid to be transferred. Clean pump
strainer basket, open and check for clogging blockage.
SYMPTOM II - MOTOR DOES NOT TURN
PROBABLE CAUSES AND RECOMMENDED ACTION:
a. No Power to Motor
Check all power switches are on, check that fuse or circuit breaker is
correctly set, check motor wiring at terminals.
b. Pump Jammed
With power off, turn shaft, it should spin freely. If not, an Electrician should
investigate.
SYMPTOM III - LOW FLOW
PROBABLE CAUSES AND RECOMMENDED ACTION:
Clogged strainer basket. (See SYMPTOM I).
Suction air leak. (See SYMPTOM I).
Closed valves or blocked lines. (See SYMPTOM I).
SYMPTOM IV - MOTOR RUNS HOT
These motors will run hot to the touch. Thermal overload protection will function to turn
off if there is an overload or high temperature problem. Excessive heat can be caused
by the following:
PROBABLE CAUSES AND RECOMMENDED ACTION:
a. Low Voltage or Incorrect Voltage
Electrician to replace bearings in motor.

Page 6 of 11
IN0021 Rev11 Dec 2020
SYMPTOM V - NOISY OPERATION OF PUMP
Probable Causes and Recommended Action:
a. Air Leak in Suction Line
Check suction line. Repair any leaks.
b. Restricted Suction Line due to Blockage or under size pipe, result
high vacuum reading at pump suction
Remove blockage or increase pipe size. Make sure strainer basket is
clean, check all valves are open.
c. Foreign Matter in Pump Impeller
Dismantle pump and remove foreign matter from impeller.
d. Cavitation
Improve suction conditions if pump is 'starved' of flow e.g. reduce suction
lift, increase pipe size and reduce number of valves and connection in
pipeline. Increase discharge pressure and reduce flow by throttling back
discharge valve.
SYMPTOM VI - MOTOR OVERLOAD PROTECTION 'KICKS-OUT'
PROBABLE CAUSES AND RECOMMENDED ACTION:
a. Low Voltage due to undersized wire or low incoming
voltage
Electrician to check with voltmeter. Increase size of wire supply. Report
low voltage to Authorities, voltage at motor must be within 10% of motor
nameplate voltage.
b. Overload due to binding in pump or wrong size impeller fitted
Indicated by high amperage readings on motor, binding shaft. Dismantle
unit and correct.
