Installation, Operation, Repair and Parts Manual

Description

Hypro centrifugal pumps are designed for agricultural and industrial spraying and transfer of a variety of fluids: water, insecticides, herbicides, wettable powders, emulsives, liquid fertilizers, etc. Polypropylene centrifugal pumps can also be used to pump acid fertilizer, calcium chloride and other highly corrosive liquids such as sulfuric and phosphoric acids.

02/00

Hypro Series 9300 hydraulic motor-driven centrifugal pumps provide smooth performance. They can be conveniently mounted on the tractor or sprayer, becoming part of the vehicle’s hydraulic system and freeing the PTO for other uses. The Hypro “close coupled” design reduces the mounting space required, eliminating long shafts and couplers between the pump and motor.

General Information—Hydraulic Systems

Hydraulic Pumps

Hydraulic pumps come in two basic types:

• Constant displacement - which will continue to put out its rated flow regardless of pressure, until the relief valve bypasses the flow.

• Variable displacement - which will produce only the flow needed by the implement until the total pump output is reached. If less than the full pump output is required, an automatic stroke control mechanism decreases the pump output to maintain a constant pressure and flow. The output varies according to demand.

Open Center Spool Valve In Neutral Position

Figure 1

Spool Valves

There are two basic types of spool valves used in conjunction with these pumps — Open and Closed Center. In the Open Center Valve (See Figure 1), the flow goes straight through the valve when in the neutral position. This type is used for constant displacement pumps where the flow should never be shut off.

Three Systems

Fitting these components together and installing a motor, we have one of the three types of systems: Open Center, Closed Center (pressure compensated) and Closed Center Load Sensing (flow and pressure compensated).

Open Center Systems

In an Open Center System, the hydraulic pump puts out a constant flow. If the pump puts out more oil than the motor can use, a portion of the oil must be bypassed around the motor. When the oil is bypassed around a loop and does no work, the energy put into it by the pump turns into heat. Therefore, the amount of oil bypassed should be kept to a minimum. Use the largest motor possible.

Closed Center (Pressure Compensated) Systems

The Closed Center Pressure Compensated system has a variable displacement pump which will deliver flow at the necessary rate to maintain a specified pressure. It is desirable to equip implements with a motor of a low flow range that will cause the pump to operate between 1800 and 2100 psi [124 and 145 BAR]. A motor that requires a large volume to obtain the correct implement speed usually causes the hydraulic pump in a closed center system to operate at a lower pressure than desirable. This low pressure results in unnecessary flow and the generation of heat that lowers the lubricating quality of the oil and can damage transmission parts. Use the smallest motor possible.

The Closed Center Valve (See Figure 2) is used with variable displacement pumps. The flow is completely shut off in the neutral position, causing the pump stroke to adjust to zero flow. The flow stops, but the pump maintains a static pressure up to the valve.

Hydraulic Motors

Figure 3 shows an internal gear motor (Gerotor) where pressure causes the cavities between the gears to expand on one side, developing torque. The Gerotor type of hydraulic motor is used on Hypro pumps for its superior performance characteristics, including cooler running and higher rpm capabilities.

Closed Center Load Sensing Systems (Flow and Pressure Compensating)

The Closed Center Flow Compensated System is a variation of the pressure compensated system, designed primarily for more efficient operation and the generation of less heat. It works on the principle of maintaining a constant pressure drop from the pump to the work port of the selector valve. Any variation in demand at the motor will cause a change in flow. The system senses this change in flow due to the change in pressure drop across the valve, and causes the pump to compensate by varying the pump flow. No restrictor is used in the pressure line and no oil is bypassed.

Installation Instructions

All Models — Open Center Systems

Models include Tank Port Adapter with built in Check Valve Assembly and Pressure Port Adapter.

HM2C and HM4C Models Only — Closed Center and Small Open Center Systems.

Models include Tank Port Adapter with built in Check Valve Assembly and Pressure Port Adapter with three different size metering orifices and HM4C models. Remove orifice for use with closed center systems with flow control such as John Deere closed center systems. Also remove for small open center systems with a maximum flow of 8 gpm [30.28 lpm] for HM2C Model; 10 gpm [37.85 lpm] for HM4C Model. If necessary, the pressure port adapter may be used without a metering orifice installed in any closed center system, provided the pressure differential across the hydraulic motor does not exceed 1800 psi (12.4 Mpa).

Preliminary to Mounting

Consult the owners manual to determine the type and capacity of the hydraulic system. Make sure the hydraulic system is recommended to operate with a continuous load. Refer to the Pump Selection Guide to confirm you have the proper pump for your hydraulic system.

Check to see that the Pump Impeller can be turned by hand. (Turn the shaft clockwise using a deep socket wrench on the impeller nut.) If it cannot be turned, open the Pump Casing to look for obstructions. Clean out any corrosion build up where the casing fits over the eye of the Impeller.

The Inlet Line

To get the full capacity from the pump, the inlet line should be the same size as the pump inlet port. A smaller size line can be used to lower pump output, but the inlet line must be at least one size larger than the outlet line. (Example: If the outlet line is 3/4"[19 mm], use 1" [25.4 mm] inlet line.) The line must be free of air leaks. Use good quality hose that cannot be collapsed by suction. Relief valves are not normally recommended to regulate spray pressure with centrifugal pumps.

Strainer Installation

While line strainers are recommended on the inlet side for roller pumps, piston pumps and other positive displacement pumps, the recommended placement of a strainer for a centrifugal pump is in the outlet line. This will eliminate any possible restriction that the strainer could create if it were installed in the inlet side.

The best location in the discharge line is immediately after the pump. The alternate location is in the inlet side if the strainer’s capacity is adequate for the pump’s required flow. If the strainer is installed in the inlet side, the strainer screen should be checked regularly to prevent clogging that will result in cavitation.

Priming the Pump

The Pump must not be run dry.

Before starting the pump, the inlet line and pump must be filled with liquid and all discharge lines must be open. On self-priming models, only the pump chamber needs to be filled with liquid. The pump must not be run unless it is completely filled with liquid because there is a danger of damaging the mechanical seal, which depends on the liquid for its lubrication.

Non-self-priming models should be mounted below the level of the liquid. The suction line should slope down to the pump and be free of dips and bends. If this cannot be done, a foot valve should be installed in the end of the inlet line so that the line can be completely filled with liquid before starting the pump.

For best priming results, the top vent plug should be removed from the pump casing, and a vent line (1/4" [ 6.35 mm] tubing is sufficient) should be installed running back to the top of the tank. This line prevents air lock, and allows the pump to prime itself by bleeding off trapped air. The small stream of liquid that returns to the tank during operation is negligible. The discharge from this line should be positioned in the tank above the high liquid level. Self-priming models can be primed by removing the top vent plug and filling the priming chamber. The priming chamber will fill to the level of the inlet port. After use, the priming

chamber should be flushed and drained to avoid chemical corrosion and damage from freezing. Drain by removing the lower drain plug.

Controlling the Pump Flow

The best way to control the flow is by incorporating two control valves in a pipe tee immediately after the strainer in the discharge line. This permits controlling agitation flow independently of nozzle flow.

In any centrifugal pump, it is the large volume of liquid which puts load on the drive. Use only the flow needed to develop the pressure required at the boom and to maintain adequate agitation. Hydraulic motor-driven centrifugal pumps are easily adjusted to the exact flow required, as explained in the Operating Instructions of this manual.

Hooking Up the Hydraulic Motor to the Tractor Hydraulic System

Hypro Series 9300HMC hydraulic motor-driven pumps can be mounted on either the tractor or sprayer. When hooking up, make sure that no dirt or liquid gets into the hydraulic motor. Keep all hydraulic connections clean. Be sure to connect the hydraulic motor into the system correctly by putting the pressure line to the Pressure Port Adapter and return line to the Tank Port Adapter. The port adapters on the hydraulic motor are sized to accommodate 1/2" NPT fittings. For maximum

performance, the hydraulic lines should also be at least 1/2" [12.7 mm] in size. For lines longer than 8 feet [2.44 m] or for the HM3C models, hydraulic line size should be at least 3/4" [19.05 mm] in order to reduce heat generation.

The tank (OUT) port adapter with a built-in check valve assembly will guard against reverse operation — allowing you to reverse oil flow to operate other equipment. This adapter must not be removed. On HM2C and HM4C model pumps, the pressure (IN) port adapter is a two-piece assembly consisting of an open (unrestricted) adapter with three orifices packed loose with the pump (See the Operations Section).

When using the HM2C or HM4C unit on any flow compensated (load sensing) closed center system, or any small open center system with a maximum flow of 8 gpm [30.28 lpm] for HM2C or 10 gpm [37.85 lpm] for HM4C, the metering orifice should be removed from the pressure port adapter. When using these units on flow compensated systems, connect to the motor priority circuit if your tractor has one.

Standard spool valves, which are found on all tractor hydraulic systems, can cause potentially damaging high peak pressures in the hydraulic system when closed, because of abrupt shutoff of oil flow in both the supply and return lines. When shutting off the pump, move the selector to the FLOAT position to allow the centrifugal pump to come to a stop gradually.

Operation

Open Center Systems— All Models Adjusting Centrifugal Pump Output

HM1C and HM3C motors have a bypass screw set 1-1/2 turns from fully closed at the factory. HM2C and HM4C have the bypass screw fully closed from the factory.

1. Open the bypass adjustment screw 2-1/2 turns from fully closed. Turn the bypass screw in to achieve the flow for the desired gpm and psi.

2. Start the tractor. Leave the directional valve in the neutral position and allow hydraulic oil to circulate for approximately 10 to 15 minutes or until adequately warmed.

4. Prime the centrifugal pump with all valves open (See the Installation Instructions and System Configuration Diagram).

5. Close the agitation line valve and keep the control valve and the boom shut-off valve open. Note the spray pressure.

7. Open the agitation line valve until you have desired circulation in the tank. Recheck the spray pressure. If it is too low, close down the agitation line valve until the desired spray pressure is reached. If the spray pressure

is too high, throttle the centrifugal pump by closing down the control valve.

Closed Center (Pressure Compensated) — HM2C and HM4C models only

On a pressure compensated system the amount of oil that is allowed to flow through the hydraulic motor is regulated by a metering orifice in the pressure port adapter. Three different sizes of orifices are supplied with the HM2C and HM4C model pumps to allow flexibility in the flow required for individual sprayer needs.

The smaller the orifice the less hydraulic oil goes through the motor, so the pump will run slower and the flow of liquid pumped and the spray pressure will also be less. As the hydraulic oil flow is increased (by installing a larger orifice), the amount of liquid being pumped and the spray pressure is also increased.

Installing and Removing Metering Orifice

1. Shut off the hydraulic system.

2. Disconnect the line to the pressure port of the hydraulic motor.

3. Remove the adapter from the motor using a 1-1/16'' wrench.

-5-

Page 6

4. Make sure the O-ring is on the metering orifice before installing into port adapter.

5. The orifice is removed or installed in the port adapter by tapping either in or out of the adapter.

A. To remove — tap the orifice out from the small end

of the adapter.

B. To install — tap the orifice in from the large end of

the adapter. The orifice is seated when a snap sound is heard.

Adjusting Centrifugal Pump Output

1. Open the Bypass Adjusting Screw in the Hydraulic Motor three (3) turns.

2. Start the tractor and allow the hydraulic oil to circulate for approximately 10 to 15 minutes or until adequately warmed.

3. Close and lock down the bypass adjusting screw in the hydraulic motor.

4. Prime the centrifugal pump with all valves open (See Installation Instructions and System Configuration Diagram).

5. Close the agitation line valve and the control valve; open the boom shut off valve.

6. With the pump running, open the control valve until the pressure gauge indicates the desired spraying pressure.

7. Open the agitation line valve until sufficient agitation is observed. Then, if spray pressure drops, readjust the control valve to restore to the desire pressure.

8. If a sufficient boom pressure cannot be attained, install the #2 size orifice and repeat Steps 5 through 7.

9. If a sufficient boom pressure still cannot be attained with the #2 size orifice, install the #3 size orifice and repeat Steps 5 through 7.

10. If a sufficient boom pressure still cannot be attained with the #3 size orifice, remove the orifice and repeat Steps 5 through 7.

This system maintains a constant flow of hydraulic oil for a given pressure drop. The flow is adjustable with a flow control valve installed in the hydraulic system (Such as the Tortoise/ Hare control on John Deere tractors). Because this system has adjustable flow, there is no need to bypass hydraulic oil as in an open center system, or to restrict the flow with orifices as in a closed center pressure compensated system.

Adjusting Centrifugal Pump Output

1. Make sure the orifice from the pressure port adapter of the hydraulic motor has been removed (HM2C and HM4C models only).

2. Close and lock down the bypass adjusting screw in the hydraulic motor.

3. Set the tractor hydraulic flow control valve for minimum hydraulic oil flow to the remote outlet (Tortoise position).

4. Start the tractor and allow the hydraulic oil to circulate for approximately 10 to 15 minutes or until adequately warmed.

5. Prime the centrifugal pump with all valves open (See the installation instructions and system configuration diagram).

6. Close the agitation line valve and open the control valve and the boom shut-off valve.

7. Slowly adjust the tractor hydraulic flow control valve until the desired boom pressure is attained.

8. Open the agitation line valve until sufficient agitation is observed. If spray pressure drops, readjust the tractor hydraulic flow control valve to restore it to the desire pressure.

Flush Pump After Use

One of the most common causes for faulty pump performance is gumming or corrosion inside the pump. Flush the pump and entire system with a solution that will chemically neutralize the liquid pumped. Mix this solution according to the manufacturer’s directions. This will dissolve most residue remaining in the pump, leaving the inside of the pump clean for the next use.

To Prevent Corrosion

Closed Center (Load Sensing) — All Models

Many tractors are being introduced with load sensing systems (also referred to as flow and pressure compensated systems) which simplify system setup and eliminate many of the problems associated with using the wrong size pump motors on a given hydraulic system. Usually, any of Hypro’s 9300HMC models may be used on this type of system, provided the hydraulic system produces sufficient oil flow for the hydraulic motor being used (Refer to the Pump Selection Guide).

After cleaning the pump as directed above, flush it with a permanent type automobile antifreeze (Prestone®, Zerex®, etc.) containing a rust inhibitor. Use a 50% solution, half antifreeze and half water, or fill the pump with FLUID FILM and then drain it. A protective coating of FLUID FILM® will remain on the inner pump surfaces. Save the excess FLUID FILM® for the next application. Plug the ports to keep out air during storage. For short periods of idleness, noncorrosive liquids may be left in the pump, but air must be kept out. Plug the ports or the seal port connections.

Make sure the Spacer ring between the seal and Bearing is free floating (not binding).

Should the Main Needle Bearings in the Hydraulic Motor need replacement, a new Body and/or End Plate, with the Main Bearing already installed, must be used. If this occurs, check other internal parts of the Motor for damage and wear.

To Install the Shaft Assembly in the Motor Body

1. Place the Shaft Assembly into the Motor Body bearing bore with threaded end up (See Figure 14).

Figure 14

2. On arbor press, place Body on arbor press fixture.

Make sure the surface edge of the fixture is smooth and clean.

An un-threaded piece of pipe (1" dia. x 4" [25.4 mm x 101.6 mm] high) is needed to support the outer bearing race on the shaft ball bearing. Place this pipe over the shaft and press shaft assembly down until retaining ring can be installed in its groove in the bearing core of the motor body (Figure 15).

Figure 15

Reassembly of Remaining Hydraulic Motor Parts

1. Place Motor Body in a vise with large end of Shaft facing up.

2. Install the O-ring in the Body.

3. Install the Woodruff Key or Roll Pin on the Shaft. Place the Inner Gear of the Gerotor onto the Shaft making sure Gerotor slot lines up with the key in the shaft.

4. Install the outer portion of the Gerotor, making sure the Gerotor is centered within the O-ring groove on the Body.

5. Install the Gerotor Housing, making sure the pins in the Gerotor Housing line up with their respective holes in the Body.

6. Lightly lubricate the area between the Inner and Outer Gerotor and the Outer Gerotor and Gerotor Housing with hydraulic oil or mineral oil.

Special attention should be exercised when working with retaining rings. Always wear safety goggles when working with spring or tension loaded fasteners or devices.

7. Install O-ring on the motor end plate.

8. Place end plate on gerotor housing, making sure holes in end plate line up with pins in the gerotor housing.

9. Install four Socket Head Cap Screws in Motor End Plate and, using a 1/4" Allen wrench, tighten Cap Screws alternately and evenly, in a crisscross pattern to approximately 15 foot pounds [ 20 Nm] of torque.

10. Install the Thread Seal Gasket on the Bypass Adjusting Screw. Put the Gasket on from the slotted end and turn until four threads on the Screw are showing. Install the Washer and the Nut. Install Bypass Adjusting Screw in the Motor end plate.

A. For closed center hydraulic systems, turn the Bypass

Adjusting Screw in until it bottoms out in the End Plate. Tighten nut down with 9/16" box end wrench.

B. For open center hydraulic systems, turn the Bypass

Adjusting Screw in until it bottoms out in the End Plate; then turn back out 1

⁄2 full turns. Holding the Bypass

Adjusting Screw with a screwdriver, tighten Nut. (Motor will then have to be readjusted to tractor system.)

11. Replace O-ring on both port adapters.

12. Install Pressure Port Adapter and Tank Port Adapter back onto the Motor. (For ease of installation, tighten the Pressure Port Adapter first, then the Tank Port Adapter.)

13. Remove Hydraulic Motor from the vise. Turn Shaft by hand to check for binding.

14. Install Slinger Ring over Motor Shaft.

15. Install Motor into Pump Mounting Flange. Insert four Hex Head Bolts; then, alternately and evenly tighten them.

[For polypropylene models secure the Hydraulic Motor to the Mounting Flange with four Hex Head Cap Screws and Nuts. The Nuts should be visible when the assembly is complete.]

The Woodruff Key can slide up behind the Inner Gear of the Gerotor when the Gear is installed. Make sure the Key is visible in the slot after the Gear is in place.
