1 Instruction Manual
1.1 INTRODUCTION
The MILROYAL
®
D Controlled Volume Pump is a
reciprocating plunger, positive displacement pump
designed to deliver accurately measured liquid
volumes against a positive differential pressure
(or head) between pump suction and discharge.
Precision built, the pump performs this function with
a repetitive accuracy of plus or minus one percent
of mean delivered volume.
Basically, the pump consists of a drive unit, plunger
and displacement chamber or liquid end in which
the plunger reciprocates. The pump delivers a
controlled volume of liquid with each discharge
stroke.
Pump capacity is adjustable by changing plunger
stroking speed and / or length. Capacity adjustment
can be made manually or automatically by
signal from remote process control instruments.
Selection of capacity control methods is determined
by the nature of the application.
1.2 UNPACKING
Pumps are shipped Free on Board (FOB) from
the factory and title passes to the customer
when carrier signs for receipt of it. The customer,
therefore, must file damage claims with the carrier.
The shipping crate should be carefully examined
upon receipt from carrier to be sure there is no
obvious damage to the contents. Open the crate
carefully, as there are sometimes accessory items
fastened to the inside of the crate which may be
lost or damaged. Examine all material inside crate
and check against packing list to be sure that all
items are accounted for and undamaged.
1.3 MOUNTING (Refer to Figure 1)
Support the pump firmly in a level position on a
solid foundation, preferable with the base above
floor level to protect it from wash downs and
provide easier access for service. This model
pump is provided with three tie-down points to
accommodate anchor bolts. Table-top operation
is possible without need for tie-down with 1/8” or
1/4” plunger diameter liquid end, but tie-down is
necessary for 7/16” and 5/8” plunger diameter liquid
ends. Up to six units can be easily multiplexed to
a single standard motor without special support.
1.4 PIPING
1.4.1 General Information
1. Use piping materials that are resistant to
corrosion by the liquid being pumped. Use
care in selection of materials to avoid galvanic
corrosion at points of connection to the pump
liquid end.
2. Use piping sufficiently heavy to withstand
maximum pressures.
3. Blow out all lines before making final connections
to pump.
4. Provide for pipe expansion when hot fluids are to
be pumped. Support piping so that pipe weight
is not placed on the pump. Never spring piping
to make connections.
5. Piping should be sloped in a manner to prevent
trapping of vapor pockets. Vapor present in liquid
end will cause inaccurate pump delivery.
