PLEASE NOTE: THIS EQUIPMENT HAS BEEN DESIGNED TO PROVIDE RELIABLE SERVICE. HOWEVER BEFORE ATTEMPTING TO INSTALL, OPERATE OR SERVICE THE EQUIPMENT, THIS INSTRUCTION MANUAL SHOULD BE READ, UNDERSTOOD AND OBSERVED. FAILURE TO D0 SO CAN RESULT IN IMPROPER OPERATION WITH POSSIBLY HAZARDOUS RESULTS.
INTRODUCTION
This book provi des installat ion, operating and maintenance ins tructions for t he Encore Plunger Meterin g Pumps; here -in-after refe rred to as the pum p or meteri ng pump. The pump provides accurate metering and transfer of a wide variety of chemicals. It is available in fo ur head s izes, f our gear r atios, di rect or pulley dr ive con figuratio ns and a single and double simplex configuration. A non-loss-of motion, stroke adjustment is used to vary the stroke for a more smooth pumping action. Non-loss-of motion is achieved through t he use of a vari able eccentric mec hanism. Stroke a djustment is done either manually or with an optional electric stroke length positioner.
An optional vari able speed dri ve controls dri ve motor spee d variations thro ugh signals received from external sources.
When an electri c s troke le ngth pos iti oner or va ri able spe ed dr ive is use d wit h the p ump, a separate instruction manual covering the particular equipment used will be furnished.

2.1 GENERAL INFORMATION
To provide satisfactory service, the Encore metering pump must be installed properly in accorda nce with the following instructions. These instructions must be followed or operational difficulties, lack of accuracy and possible damage to the pump mechanism may occur.
2.2 UNPACKING
When unpacking, check all items against the packing list to be sure no parts are missing or discarded with the packing material. Wherever possible, unpack the pump at the installation site.
2.3 MOUNTING THE PUMP
Pump location is important to the operation of the pump. Select a place that is dry and provides a level base for the pump. Allow work space around the pump for inspection, adjustments and servicing. Be sure it is near a power supply and located where the discharge line may be conveniently run to the point of application. It is recommended that the pump be installed with a flooded suction (see Dwg 440.400.4-PLUNGER). A carefully considered and correct installation will help provide satisfactory performance.
When installing the equipment, proceed as follows:
a. Select the appropriate dimension and / or installation drawing to be sure the location
selected will meet all requirements. See the Typical installation drawings.
b. Mount the pump on the bench or shelf on which it will be located.
c. Connect to a power supply matching the characteristics specified on the motor
nameplate in accordance with local code requirements. Sufficient flexibility must be provided in the connection to permit adjustments. Be sure to provide a shut-off switch in the power supply.
NOTE: Field wiring must conform to local electrical codes.
WARNING: TO AVOID POSSIBLE SEVERE PERSONAL INJURY OR DAMAGE TO THE EQUIPMENT, CONSULT YOUR WPS REPRESENTATIVE IF THE PUMP IS TO BE USED UNDER CONDITIONS OTHER THAN ORIGINALLY SPECIFIED AND IF THERE IS ANY QUESTION REGARDING THE SlZE OF THE DISCHARGE LINE.
d. If a pulsation dampener is required to reduce pressure peaks, install it in the discharge
line. See the Typical Installation drawing. The dampener will minimise vibrations and wear due to long lines and / or high stroking speed.
e.
Connect rigid pipe to the suction connection on the pump and run a line without traps to the bottom of the solution container. Install a strainer.
2.4 PIPE LINE DIAMETER
General Guidelines: To determine the proper diameter of the suction line and discharge lines, the following should be taken into consideration; cavitation and high pressure drop.
To Avoid Cavitation: a) For shorter pipe runs (less than 3 metres), use pipe diameter at least equal to the valve
connection. b) For longer (greater than 3 metres), use pipe diameter at least one size larger than valve
connection.
OR
Use this formula to compute fluid velocity in meters / second
Velocity = Discharge (Q) x 0.35
d
2
Where
Q = feed rate in litres per hour
d = inside diameter of pipe in mm
V = velocity of fluid in meters /second
Select pipe diameter so that the velocity in the suction line does not exceed 0.2 metres / sec.
2.5 PRESSURE RATINGS
Pressure Ratings
Plunger Size
Maximum working Pressure (Bar)
6p & 12p (3/8” &3/4” dia) 10 & 20 mm
200 bar
24p ( 1 ½” dia) 38 mm
50 bar
32p (2” dia) 50 mm
30 bar
WARNING: TO AVOID POSSIBLE SEVERE PERSONAL INJURY WHEN HAZARDOUS CHEMICALS ARE PUMPED AND / OR ELEVATED PRESSURE / TEMPERATURES ARE ENCOUNTERED, USE RIGID PIPE.
2.6 INSTALLATION
The installation drawings and associated wiring diagram for the various pump configurations are located at the end of this section.
a. Unnecessary restrictions in piping.
b. Thin walled hose, which may collapse due to a small cross-sectional area during suction stroke, thereby causing both a high pressure drop and velocity.
c. Difficult to vent bends in the line, where air may be trapped, impairing the accuracy of feed rate.
d. If storage container is used, the suction line should be connected above the container's bottom to avoid any deposits on the bottom which can enter the suction line. Such deposits may damage the pump valves and impair the function of the pump.
e, If the liquid to be pumped contains un-dissolved particles, it is recommended that an adequately dimensioned strainer be installed in the suction line. It is preferred that one size larger than the pipe diameter be used.
Recommended minimum height from floor to valve connections should be 12 inches (305 mm)
Dimensions are feet and inches (indicates mm)
