2 Introduction
The MS-53 Laboratory Mixer is used to ensure that samples of crude oil or other products
extracted from a pipeline or a cargo are thoroughly mixed prior to laboratory analysis, to
ensure that the small amount of sample is truly representative of the whole.
The sample is normally collected in Jiskoot Type PR-23 (9 litre) or PR-53 (18 litre) portable
Sample Receivers over a period of some hours. It may be many hours before it is analysed
and during this time some of the water will fall out and separate.
The standard MS-53 Laboratory Mixer is capable of mixing viscous products of up to 500 Cst
(at operating temperature). Alternative motors and pumps may be required for higher
viscosity applications.

Issue No 6 Page 5
3 Operating Instructions
The MS-53 Laboratory Mixer is simple to operate.
The Mixer must be firmly located on a suitable bench and connected to a suitable electrical
supply.
The 3/4" suction and 1/2" discharge hoses must be connected to the appropriate connections
of the Sample Receiver. Ensure that the quick release couplings are connected properly by
pulling gently on the hoses.
Apply power to the Mixer. Mixing time is a function of gravity, viscosity and various other
factors. Tests have shown that the Laboratory Mixer will successfully mix a variety of oils
within 5-10 minutes, however, the optimum mixing time will vary depending on the
composition of the oil.
When crude oil is sampled at a high temperature, allowed to cool and then reheated,
condensation may form in the Sample Receiver. If this occurs, ensure the can is briefly
shaken by hand to remove water droplets from the top of the receiver.
In some instances the pump may need assistance in priming. To do this lift the receiver up
with the mixer running until the pump primes.
NOTE: To avoid damage to the pump, the Laboratory Mixer should not be operated for periods exceeding
3 minutes if no product available.
When the oil is thoroughly mixed, draw off a sample from the needle valve into laboratory
glassware for analysis. Alternatively, a septum may be fitted to the Mixer to enable the
sample to be taken using a syringe. It is recommended that the initial 10-20ml of sample be
discarded, to ensure all equipment is thoroughly flushed.
When sufficient sample has been obtained, switch off the mixer and thoroughly clean all
equipment to prevent cross contamination.
4 Full Functional Description
The MS-53 Laboratory Mixer consists of a loop drawing oil from the lowest point in the
Sample Receiver through the electric motor driven gear pump. The oil is discharged from the
pump through the static mixer and returned to the receiver. The return pipe of the Sample
Receiver is pointed down, tangentially towards the wall of the receiver to promote extra
mixing.
The Laboratory Mixer is fitted with a needle valve to enable the sample to be drawn off into
laboratory glassware. In addition, a septum may be fitted to enable a sample to be drawn off
via a syringe.
The MS-53 Laboratory Mixer is normally supplied with an electric motor, but is also available
with a pneumatic motor for applications where electricity is not an available power source.
5 Utilities Reference
Electrical Requirements 100/110 or 240/220 Volts, 50 or 60 Hz to suit motor supplied.
Power Requirement 0.5KW
Pneumatic Option 3Barg/45psig lubricated air supply.

MS-53 Laboratory Mixer
Issue No 6 Page 6
6 Installation Details
The Laboratory Mixer must be installed and operated in compliance with any applicable
electrical hazardous area regulations. The electrical supply should be connected to the motor
isolating switch via a suitably certified M20 cable gland, ensuring that earth continuity across
the switch is maintained.
7 Maintenance & Troubleshooting
Other than cleaning after use, the MS-53 Laboratory Mixer requires minimal maintenance.
The septum rubbers are self-sealing, however if a leakage is noted, they must be replaced
with new rubbers.
Both Laboratory Mixer and Sample Receiver must be cleaned to prevent cross-contamination
of samples.
The recommended method for cleaning this equipment is to use a solvent and an inert gas
(e.g. Nitrogen) as follows:-
1) Remove Sample Receiver from Laboratory Mixer and empty.
2) Re-connect Sample Receiver and run Laboratory Mixer for approximately 15
seconds.
3) Disconnect and empty Sample Receiver.
4) Add 2 litres of solvent (Toluene or Kerosene).
5) Turn on Laboratory Mixer and circulate for one minute.
6) Turn off and remove pump suction hose (3/4" connector)
7) Connect suction to inert gas source (Nitrogen) NOT compressed air.
8) Carefully blow out Laboratory Mixer with inert gas. NOTE: The gas pressure will
relieve through the Sample Receiver relief valve.
9) Remove Sample Receiver. Clean with solvent and leave inverted with cover
removed to drain.
DO NOT UNDER ANY CIRCUMSTANCES:-
1) Use compressed air for purging.
2) Run the Laboratory Mixer with the discharge hose disconnected or shut off - high
pressures will build up and may cause the hose to rupture.
3) Run the Laboratory Mixer unprimed or with solvent for long periods
8 Sub Supplier Information
8.1 Electric motor
The electric motor requires no routine maintenance. In the event of a fault, the motor should
be replaced or fully overhauled by a qualified repair shop.
8.2 Gear Pump Overhaul
The gear pump has minimal serviceable components. A replacement seal kit is available for
site replacement if required, but as any wear on the gears and body faces causes loss of
performance, a replacement pump is recommended.
8.3 Pneumatic Motor
Before dismantling the pump, using a broad felt tip marker pen, draw a line on the pump outer
casing from the foot/flange casting across the centre body casting to the end cover casting.
1) Slacken and remove the 4 socket head set pins.
2) Remove end cover casting.

3) Remove centre body casting.
4) Remove gears and shafts.
5) Remove dowels.
6) Clean components, removing traces of paint, and/or gasket material from body sides.
8.3.1 Examine:
1) Shafts for signs of wear (a maximum reduction of .002” difference from diameter of
unworn part of shaft is acceptable).
2) Gears, tooth form and gear end faces for wear, scuffing or damage, and replace if
necessary.
3) Lip Seal/s for damage caused by dirt or metal particles, etc. and replace if necessary.
NOTE: With double lip seal arrangements, ensure that the seals are re-fitted facing exactly the same
direction as the seals they replaced.
8.3.2 Reassembly
1) Ensure that all components are clean and free from dirt and paint etc.
2) Measure the body width and gear width and fit paper gaskets to allow a maximum of
0.002" running clearance.
3) Fit dowels.
4) Align the components to the felt marker line and re-assemble in reverse order to the
dismantling procedure.
5) Tighten the 4 socket head set pins evenly and diagonally whilst rotating the driveshaft
by hand. Ensure that the pump rotates evenly for the full 360owithout tightness.
Should tightness occur, slacken set pins and try again.
6) If the pump cannot be assembled as indicated, examine gears for damage and, if
satisfactory, fit an extra gasket to one face and repeat from 5 above.

understand the Safety Notice statements in this manual. For your protection, do not install, operate or
attempt to perform maintenance procedures until you understand the Warning and Caution statements. A
Warning statement indicates a possible unsafe condition that can cause harm to personnel. A Caution
statement indicates a condition that can cause damage to equipment.
Important: This instruction manual is not intended to include a comprehensive listing of all details for all
procedures required for installation, operation and maintenance. This manual describes general
guidelines that apply to most of the motor products shipped by Baldor. If you have a question
about a procedure or are uncertain about any detail, Do Not Proceed. Please contact your Baldor
distributor for more information or clarification.
Before you install, operate or perform maintenance, become familiar with the following:
SNEMA Publication MG-2, Safety Standard for Construction and guide
for Selection, Installation and Use of Electric Motors and Generators.
SThe National Electrical Code
SLocal codes and Practices
Limited Warranty
1. Most Baldor products are warranted for 18 months from the date of shipment to Baldor’s customer from Baldor’s
district warehouse or, if applicable, from Baldor’s factory. Baldor Standard–E®standard efficient motors are
warranted for 24 months. Standard–E is limited to three phase, general purpose, 1–200 HP ratings that fall under
the Energy Policy Act (EPAct). Baldor Super–E®premium efficient motors are warranted for 36 months. Baldor
IEEE841 motors are warranted for 60 months. All warranty claims must be submitted to a Baldor Service Center
prior to the expiration of the warranty period.
2. Baldor will, at its option repair or replace a motor which fails due to defects in material or workmanship during the
warranty period if:
a. the purchaser presents the defective motor at or ships it prepaid to, the Baldor plant in Fort Smith, Arkansas
or one of the Baldor Authorized Service Centers and
b. the purchaser gives written notification concerning the motor and the claimed defect including the date
purchased, the task performed by the Baldor motor and the problem encountered.
3. Baldor will not pay the cost of removal of any electric motor from any equipment, the cost of delivery to Fort Smith,
Arkansas or a Baldor Authorized Service Center, or the cost of any incidental or consequential damages resulting
from the claimed defects. (Some states do not allow the exclusion or limitation of incidental or consequential
damages, so the above exclusion may not apply to you.) Any implied warranty given by laws shall be limited to
the duration of the warranty period hereunder. (Some states do not allow limitations on how long an implied
warranty lasts, so the above limitation may not apply to you.)
4. Baldor Authorized Service Centers, when convinced to their satisfaction that a Baldor motor developed defects in
material or workmanship within the warranty period, are authorized to proceed with the required repairs to fulfill
Baldor’s warranty when the cost of such repairs to be paid by Baldor does not exceed Baldor’s warranty repair
allowance. Baldor will not pay overtime premium repair charges without prior written authorization.
5. The cost of warranty repairs made by centers other than Baldor Authorized Service Centers WILL NOT be paid
unless first authorized in writing by Baldor.
6. Claims by a purchaser that a motor is defective even when a failure results within one hour after being placed into
service are not always justified. Therefore, Baldor Authorized Service Centers must determine from the condition
of the motor as delivered to the center whether or not the motor is defective. If in the opinion of a Baldor
Authorized Service Center, a motor did not fail as a result of defects in material or workmanship, the center is to
proceed with repairs only if the purchaser agrees to pay for such repairs. If the decision is in dispute, the
purchaser should still pay for the repairs and submit the paid invoice and the Authorized Service Center’s signed
service report to Baldor for further consideration.
7. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
