INTRODUCTION

The NGP series pump is a positive displacement variable stroke metering pump. It is specifically designed to accurately meter liquid fertilizer solutions. The pump’s construction is of rigid thick walled cast iron cylinders and manifolds for durability and long life. The check valves, piston, and rod are constructed of stainless steel for improved corrosion resistance. Optionally, the pump may be purchased with stainless cylinders and manifolds.

The NGP series pump functions as a positive displacement metering device which operates in direct relati on to the ground speed through a ground drive system (model number DRV-3xxx). The application rate can be set (covered under the “Pump Setting” section) before application begins and the GPA (gallons per acre ) application will be accurate regardless of the varying speeds of the drive mechanism.

The NGP series pump may also be used with one of our hydraulic drive kits (model number VRH-xxx-xx) to provide variable rate application when used with one of many different control systems. The pump provides several advantages over other types of pumps such as: suction capability from saddle tanks, stable settings that do not vary with temperature, and proven durability and longevity.

The NGP series pump is designed to control the overall gallons of solution metered over an acre, independent of downstream discharge pressure (120 psi max). The only function of the flow divider or row orifices in a CDS – John Blue pump system is to divide liquid accurately row to row - not to meter the overall application rate.

INSTALLATION

MOUNTING

 The NGP pump should be mounted on a rigid base in a horizontal position.  The mount position should allow for a straight drive chain and proper tightness.  Chain idlers should be installed on the slack side of the drive chain.  The supplied rubber washers are installed between the pump and mount.  Caution should be exercised on implements with wings or folding members to assure that sufficient area is

allowed around the pump and plumbing to not cause contact or binding.

 Verify that the rear tractor wheel will clear the pump during sharp turns.  The oil vent plug should be installed in the oil fill located on top of crankcase.

SUCTION PLUMBING

 An adequately sized 30 mesh strainer should be installed on the suction side of

the pump and should be checked at each tank filling for debris, which could cause suction restriction, starving the pump of flow.

 The NGP pump does produce suction to pull fluid from the tank; however, it is

recommended to mount the pump level or below the tank, if possible, to assure the most effective and quickest prime.

 Install the process fluid suction line as straight as possible avoiding restrictions from kinks or e x tremely

sharp turns. This will ensure even flow during maximum pump output.

 Quick connect fittings should be checked and double checked to verify that no leakage is present. Quick

connects, although commonly necessary, quite often can produce a suction leak if installed in a bind allowing air to enter the pump, causing loss of prime and / or reduction in pump output.

 It is recommended that suction line hoses be double clamped. Again, this is an area that can produce a

suction air leak into the pump, even if no drip from the hose is present.

DISCHARGE PLUMBING  It is not recommended to install a discharge strainer as these could clog with debris causin g significant

discharge pressure and possible system damage in positive displacement pump applications.

 Flow dividers may be installed either directly on top of the discharge port or remote mounted.  Orifice applications must pay particular attention for proper orifice sizing for the specified application rate.  It is recommend that applications using a double piston pump with two flow dividers remove the common

manifold and plumb each flow divider independently to each piston to assure accuracy.

 On – The – Go Variable Rate applications require that a CDS – John Blue Co. flow divider distribution

manifold be used that will automatically and accurately adjust for varying on the go rate changes.

WARNING: The flow range of a NGP pump far exceeds the flow curve of a single orifice operating below 120 psi. For Example: An orifice application at 30 psi discharge pressure for a rate of 20 GPA @ 4 mph will produce 422 psi when the rate is adjusted to 50 GPA and ground speed increased to 6 mph.

PUMP SETTING

The NGP pump output is determined by the drive sprocket ratio and the stroke setting. There are two ways to find the proper setting for your pump:

1. Using the online flow rate calculator at www.cds-johnblue.com .The icon is on the

right-hand side of the page, and there is a mobile version available here:

2. Using the slide chart (115698-91) supplied with the pump – follow the example below:

MAXIMUM GROUND SPEED

SPROCKET RATIO

LOADED RADIUS

STANDARD SPROCKET COMBINATIONS

SPROCKET RATIO

Standard Sprocket Combinations Standard sprocket combinations may be used for equipment with only one chain from the ground or press wheel sprocket to the pump sprocket. For example: an applicator with a 60 tooth drive sprocket on the tire driving a 16 tooth driven sprocket on the pump can use the 16 to 60 mark on the slide chart.

Non-Standard Sprocket Combinations If you are using sprocket combinations with multiple sprockets, such as with a jack shaft, use the following formula to determine sprocket ratio:

For example: an applicator with a 50 tooth on the drive wheel, driving to a 24 tooth on the jack shaft, then a 36 tooth on the jack shaft driving up to a 16 tooth pump driven sprocket, would yield a 4.69 drive ratio.

Set the sprocket ratio on the slide chart using the 4.69 calculation for the example above.

LOADED RADIUS

The measurement for the loaded radius must be from the Manufacturer of the tire or be measured under loaded conditions. The loaded radius tire is always the tire that has the first drive sprocket attached to its hub.

Ground Wheel Drive Arrangement Measure the loaded radius from the center of the hub to the bottom of the tire where it rests on the ground.

Press Wheel Drive Arrangement Measure the loaded radius from the center of the press wheel shaft to where the wheel rests against the tire. The press wheel must be engaged for normal operation to give an accurate reading.

SWATH WIDTH

To determine the swath width, count the number of outlets and multiply by the distance (inches) between any two outlets, nozzles, or shanks. This assumes that all outlets are equally spaced, if outlets are not evenly spaced, figure the entire length of the boom or toolbar from end nozzle to end nozzle and allow for coverage beyond the ends. For example, an 11 row boom at 30” would have a swath width of 330”

SETTING THE PUMP

Read the desired pump setting from the bottom scale on the pump setting chart. Loosen the setting pointer nut and rotate the setting hub until the setting pointer is over the desired setting. The setting wrench will facilitate rotation of the setting hub. Once proper pump setting is achieved, tighten the setting pointer nut.

EXAMPLE:

An applicator is equipped with a NGP-6050 series pump, 11L x 15” tires, a 60 tooth drive sprocket, and a 16 tooth pump driven sprocket. It is desired to apply 33 gallons per acre on a 360” swath. The following steps will determine correct pump setting:

SET SWATH WIDTH AT DIAMOND

SET LOADED RADIUS

1 2

AT SPROCKET RATIO

1. Set loaded radius of tire (13.5”) under the sprocket combination of 16 to 60 in the top window.

2. Set the swath width (360”) under the diamond in the middle

window.

3. Read that the pump setting is approx. 9 at 33 gallons per

acre on the NGP-6055 scale in the bottom window.

4. Set the pump to setting 9 to achieve 33 gallons per acre

Note: The max. ground speed is read above the diamond as

READ PUMP

approx. 9 mph to avoid exceeding 450 pump rpm.

INITIAL PUMP START UP

Verify that all installation guidelines have been followed as outlined in the installation section of this manual.

 Fill the tank full of water to test for leaks in the plumbing system and output of the pump.  Fully open the valve at the tank allowing water to fill the suction line and check for leaks.  Set the pump to pump setting 10.  Before installing nozzles or orifices (if used), prime the pump and purge the system of air and foreign

material by slowly pulling the applicator 100 to 200 yards.

 Turn off the valve at the tank, open strainer, check for foreign material and clean the screens.  The CDS – John Blue flow divider is automatic and requires no calibration; however, if nozzles or orifices

are used, verify that the orifices are sized properly as to not produce high discharge pressure.

 Pull the machine over known acreage and verify the application accuracy with water prior to field

application of chemical. Note that tank level marks can give false readings if read on uneven ground.

PUMP CALIBRATION

The NGP pump is calibrated from the factory; however, if the setting scale, hub, or pointer is replaced, use the following procedure to calibrate the pump output with scale readings.

 Remove the valve cover and outboard cylinder (see maintenance section).  Set the pump on pump setting 5 for all pump sizes.  Rotate the crankshaft until the piston is as far in as it will go. Measure the distance from the end of the

piston to the inboard cylinder flange. Rotate the crankshaft until the piston is as far out as it will go and measure again to the same place. The difference in length is the stroke length, which at pump setting 5 should be 9/16” for the NGP-4050, 5050, 6050, & 8050, or 15/16” for the NGP-7050 & 9050.

 If the distance is less than the required amount, reset the pointer at a higher setting, if it is greater; reset

the pointer at a lower setting. Repeat this procedure to obtain the required measurement.

 Once accomplished, loosen the setting scale screws until the 5 is directly under the pointer and secure the

scale in position with the three scale screws.

 Replace the outboard cylinder and valve cover, making sure that the valves are in their proper orientation

as covered under the maintenance section.

PUMP ACCURACY

A catch test may be performed to verify accuracy (not as a calibration method) by priming the pump and catching all of the pumped fluid from the discharge for a known number of revolutions. See chart below:

Pump Series Pump Setting # of Revolutions Total Pump Output NGP-4050 8-1/4 10 1-1/2 Pints NGP-5050 8-1/4 10 3 Pints NGP-6050 8 10 3 Pints NGP-7050 8-1/4 10 5 Pints NGP-8050 8 10 6 Pints NGP-9050 8-1/4 10 10 Pints

MAINTENANCE

 Check oil daily and fill crankcase with a quality grade SAE 90 weight gear oil. Oil level must be visible at oil

level check plug on back of crankcase. The level plug is located at same height as the crankshaft.

 Lubricate all grease zerks on roller chain sprocket spacer, outboa rd cover plate, crankshaft end, and at

stuffing box flange daily. Fill zerks until grease is visibly seen seeping from mating parts. For the stuffing box flange zerk, grease will be seen seeping from the vent on the opposite side of the flange.

 Pump oil should be changed seasonal or in extreme use conditions.  Visually inspect sprocket and drive chain daily for excessive wear or corrosion. Lubricate chain regularly to

reduce corrosion. Chain alignment must be straight.

STORAGE

IMPORTANT – KEEP AIR OUT AND KEEP FROM FREEZING

Keep air out of the pump! This is the only way to prevent corrosion. Even for short periods of storage, the entrance of air into the pump causes RAPID and SEVERE CORROSION. Freezing temperatures can cause the fluid or water to freeze internally to the pump, which can cause severe damage to the wet-end castings.

OVERNIGHT

Suspension fertilizer must be flushed from the pump for ANY storage period. For Clear Liquids:

1. Steady or rising temperatures: leave pu mp and hoses filled with solution. DO NOT DRAIN nor admit air

to the pumps.

2. Cooling weather: (solution likely to salt out), fill pump with water and leave filled. DO NOT admit air.

3. Freezing temperature: fill pump with RV-antifreeze and leave filled, DO NOT admit air.

ONE TO TWO WEEKS

ACCEPTABLE: Flush pump thoroughly with 5 to 10 gallons of a solution that will neutralize the liquid last

pumped (refer to that manufacturer’s instructions). Fill with clean water and DO NOT DRAIN. Keep pump sealed to exclude air. If freezing temperatures are remotely possible, the winter storage procedure (see below) must be used to avoid damage to the pump castings.

PREFERRED: Flush pump as detailed above. IMMEDIATELY fill all passages in pump with straight RV-

antifreeze which contains a rust inhibitor. Place 1-1/2” NPT PVC plugs in the suction and discharge fittings to keep pump full and exclude air.

WINTER STORAGE

1. Flush pump as detailed above.

2. With pump set on 10, draw in straight RV-antifreeze until the discharge is clean. If system utilizes a flow divider (FD), pump the RV-antifreeze through the FD manifold until it is seen in the discharge lines. Fill pump and plug suction and discharge fittings of pump to retain RV-antifreeze.

SERVICE MAINTENANCE

Proper maintenance of the NGP pump will ensure a service life for many years. Rebuilding and / or servicing check valves, piston flange packing, piston rod packing, and crankcase compone nts is an economical way to ensure optimum service. This type of service is simple, and can be done by almost all end users. The parts list and schematic section shows the position of all service kit items, which includes all seals, packing, and gaskets. Gasket kits and component parts can be ordered through any authorized CDS – John Blue distributor.

CLEAN AND INSPECT CHECK VALVES

 Remove the valve cap exposing all 4 check valves. Take care in

removal to notice the orientation of the valves. Discharge valves use a tighter spring and are on top, flat side in. Suction valves use a weaker spring and in the bottom, flat side out.

 Valves should be removed by hand, do not use a screw driver or

pry-bar as damage can result. Push each valve disc off its o-ring seat ensuring that the spring reseats each disc evenly and that no debris is present. Inspect the o-rings for cuts or cracks which could allow air to enter or cause the discs to not seat properly.

 Check the port o-rings positioned near the top and bottom of the

inboard cylinder in an oval shaped groove. This o-ring should not be removed unless visible damage is present. The o-rings should be fully installed in the groove with no cuts or cracks. Once all valves are checked for debris or damage and o-rings are in position, re-install valves in proper orientation, replace the cover, an d tighten the bolts evenly.

PISTON PACKINGS

 With valve cover removed, remove the ½” long bolts securing the

outboard cylinder. Remove the outboard cylinder exposing the piston – gaskets, washer, and packing.

 Remove the first piston – packing, gasket, and washer; notice the

orientation of the packing lip. Remove the second piston gasket and packing from the inboard cylinder; again noticing the orientation of the packing lip.

 Inspect the packing and replace if necessary, gaskets should

always be replaced once removed. The piston - packing should be pliable and without cracks or nicks to perform properly.

 Clean the cavities of both the inboard and outboard cylinder as

well as the valve cap while disassembled. Discoloration of the plunger and / or lateral scoring of the piston can be deceiving, but not necessarily detrimental.

 Inspect piston for deep grooves, radial scoring, or severe abrasion. The best method is by feel.  Assemble in reverse manner taking care for proper orientation of the piston – packing, gaskets, and washer.

PISTON ROD PACKINGS

The rod packing consists of 2 sets of self-tightening ‘V’ rings which seal around the piston rod to prevent pumped fluid from leaking and protect the crankcase from contamination. Virtually any leakage of the pumped fluid through the vent in the side of the stuffing box is an indication that these rod packing need replacement. However, it is not uncommon for oil to drip form this drain.

Removal of rod packing:  With the valve cap and cylinders removed, remove the piston nut

and piston by rotating piston counter-clockwise, use a belt wrench

Piston Rod Packing

or cloth nearest to the nut end to prevent damage to the piston.

 Remove the stuffing box and gasket which house the wet-end

piston rod packing.

 Remove the snap ring from the end of the stuffing box, allowing

the washer, spring, and washer to slip out. The L-1031-2 insert should not be removed from the stuffing box. The rod packing set can be removed with a hook or screwdriver by prying the multipiece rod packing set out of the cavity. Once removed it must be replaced with a new service rod packing set.

 There is no snap ring on the second set closest to the crankcase

located in the crosshead guide. This set may be removed in the same manner as the first set. There is a secondary o-ring rod seal located at the bottom of the set which also should be replaced.

 Inspect the piston rod for any deep scoring and replace if necessary. A polished wear pattern may be

evident and is not detrimental; however, deep grooves indicate the piston rod assembly should be replaced.

 The crosshead guide may be removed from crankcase to allow for inspection of the connecting rod bu shing.

If damaged or slop is present, this should be replaced.

Re-assembly and replacement of rod packing:  Carefully re-install the crosshead guide and gasket and bolt to

crankcase, if removed.

 Lubricate piston rod and install o-ring first, then carefully install the

first ‘V’ ring packing set. The set consists of a bottom adapter, 4 rings, and a top adapter. Each component should be inserted one at a time and pressed firmly in place. The 4 rings have a ‘V’ shape and are oriented so as the ‘V’ point is pointed towards the crankcase, for both sets. Install the washer and spring.

 Install second set in the stuffing box in a similar manner, there is

no secondary o-ring required in this set. Install the washer, spring, then washer and hold in place with snap ring.

 Lubricate piston rod and stuffing box, then slide stuffing box carefully back over rod, being extremely careful

to push straight on the piston rod so as the rods threads do not damage the ‘V’ ring set.

 Re-assemble piston, inboard, and outboard cylinder in reverse manner. Continue with valves in proper

orientation, valve cover, and secure all bolts evenly.

 Finally, lubricate the stuffing box grease zerk until grease seeps out of the stuffing box vent hole.

CRANKCASE DISASSEMBLY

Major pump repair requires some in-depth knowledge on working tolerances for internal parts. We recommend that you contact your nearest CDS-John Blue sales and service dealer for best results in major pump repair. Shaft oil seals have been upgraded from previous L & LM series pumps to include a wiper ring. The oil seals are enclosed in a greaseable cavity to flush debris from around the seal, which is a contributing factor to premature oil seal failure. The oil seals may be replaced by following the OUTBOARD & INBOARD COMPONENTS section below. All instruction and visual representation in this section is shown with wet-end components removed which is covered in the maintenance sections preceding this section.

OUTBOARD COMPONENTS

 Remove the retaining ring, pump setting hub, and pointer.  Remove the flange cover exposing the oil seal in its cavity.  Remove the oil seal which may be done with a screw

driver, taking care not to scar the internal shaft or housing.

 Inspection of the stroke setting sleeve should be made for

wear at the seal location as well as the flange gasket for tears prior to re-assembly.

INBOARD COMPONENTS

 Remove the sprocket from shaft and sprocket spacer,

inspecting the o-ring and thrust washer for wear, cuts, or damage and replace as necessary.

 Remove the cover plate. It may be necessary to remove

any marks in the crankshaft from the sprocket / spacer set-screws with a light emery cloth in order for the cover plate to slip off with the bearing.

 Remove the oil seal with a screw driver, taking care not to

scar the housing or shaft.

 If only the oil seal is being replaced, the cover plate should be re-installed first, then the oil seal. Inspect

the shaft for wear at the seal location, as well as the cover plate gasket for tears, replace as necessary.

INTERNAL COMPONENTS

The following inspection points should be made prior to disassembly if required:

 With inboard and outboard components removed, examine for sediment in the crankcase. A small

amount of metal wear and ‘grit’ in the oil is normal, large sediment may require further disassembly.

 Check for metal and/or fertilizer discoloration to the oil. If fertilizer is present, the crankcase should be

disassembled and each component examined for rust pitting or deterioration.

 Holding the crankcase firmly, take hold of the connecting rod and push / pull. If you feel obvious end

play, disassemble all components and inspect for wear, particularly the eccentrics and connecting rod.

Page 13

INTERNAL DISASSEMBLY

Reference to the schematic section is recommended prior to disassembly of the internal crankcase components to familiarize yourself with components. The wet-end components, inboard, and outboard components should be removed prior to internal disassembly as outlined in previous sections of this manual.

 Supporting the piston rod with a wood block, locate the

crosshead pin, which connects the piston rod and connecting rod and carefully drive pin out with a hammer and punch.

 Inspect the connecting rod bushing for damage and replace as

necessary during re-assembly.

 Slide the outer eccentric and eccentric pin out of the crankcase.

 The connecting rod can then be removed by carefully sliding it

out the side of the pump at an angle.

 The shaft can then be removed as shown with the inner

eccentric still in place.

Note: Double piston pumps will require the stroke transfer

sleeve to be removed with the shaft exposing the second piston eccentric and connecting rod for removal.

 The stroke setting sleeve is then removed.

 The eccentric pins may slide out during any

part of this process and should be accounted for, single pumps utilize 1, double pumps utilize 3 [ref schematic].

 Examine all components, giving more

attention to ones showing “galling” than to ones which are undersize, yet smooth.

CRANKCASE RE-ASSEMBLY

 All components in the gasket kit should be used during re-assembly.  Reassemble the crankcase in reverse order.  When assembling the shaft, oil the shaft o-ring and carefully insert into stroke setting sleeve.  It is extremely important that all eccentric pins engage appropriate mating slots.  Coat all bolts threads with gasket sealant before installing in crankcase.
