IMPORTANT

Read the safety warnings and instructions in this manual

before pump installation and start-up. Failure to comply with

the recommendations stated in this manual could damage the

pump and void factory warranty.

When used for toxic or aggressive uids, the pump should

always be ushed clean prior to disassembly.

Airborne particles and loud noise hazards. Wear eye and

ear protection.

Before maintenance or repair, shut off the compressed air line,

bleed the pressure, and disconnect the air line from the pump.

Be certain that approved eye protection and protective clothing

are worn at all times. Failure to follow these recommendations

may result in serious injury or death.

When the pump is used for materials that tend to settle out

or solidify, the pump should be ushed after each use to

prevent damage. In freezing temperatures the pump should be

completely drained between uses.

Before pump operation, inspect all fasteners for loosening

caused by gasket creep. Retighten loose fasteners to prevent

leakage. Follow recommended torques stated in this manual.

CAUTION

WARNING

Nonmetallic pumps and plastic components are not UV

stabilized. Ultraviolet radiation can damage these parts and

negatively affect material properties. Do not expose to UV light

for extended periods of time.

Model HD20F Non-Metallic

In the event of diaphragm rupture, pumped material may enter

the air end of the pump, and be discharged into the atmosphere.

If pumping a product that is hazardous or toxic, the air exhaust

must be piped to an appropriate area for safe containment.

This pump is pressurized internally with air pressure during

operation. Make certain that all fasteners are in good condition

and are reinstalled properly during reassembly.

Take action to prevent static sparking. Fire or explosion can

result, especially when handling ammable liquids. The pump,

piping, valves, containers and other miscellaneous equipment

must be properly grounded.

Safety Information

WARNING

Pump not designed, tested or certied to be powered by

compressed natural gas. Powering the pump with natural

gas will void the warranty.

Use safe practices when lifting.

WARNING

The use of non-OEM replacement parts will void (or negate)

agency certications, including CE, ATEX, CSA, 3A and EC1935

compliance (Food Contact Materials). Warren Rupp, Inc. cannot

ensure nor warrant non-OEM parts to meet the stringent

requirements of the certifying agencies.

8 • Model HD20F Non-Metallic

Air-Operated Double Diaphragm (AODD) pumps are powered by compressed

air or nitrogen.

The main directional (air) control valve ①distributes compressed air to

an air chamber, exerting uniform pressure over the inner surface of the

diaphragm

②. At the same time, the exhausting air ③ from behind the

opposite diaphragm is directed through the air valve assembly(s) to an

exhaust port ④.

As inner chamber pressure (P1) exceeds liquid chamber pressure (P2),

the rod ⑤connected diaphragms shift together creating discharge on one

side and suction on the opposite side. The discharged and primed liquid’s

directions are controlled by the check valves (ball or ap)⑥orientation.

The pump primes as a result of the suction stroke. The suction stroke lowers

the chamber pressure (P3) increasing the chamber volume. This results in

a pressure differential necessary for atmospheric pressure (P4) to push the

uid through the suction piping and across the suction side check valve and

into the outer uid chamber ⑦.

Suction (side) stroking also initiates the reciprocating (shifting, stroking

or cycling) action of the pump. The suction diaphragm’s movement is

mechanically pulled through its stroke. The diaphragm’s inner plate makes

contact with an actuator plunger aligned to shift the pilot signaling valve.

Once actuated, the pilot valve sends a pressure signal to the opposite end

of the main directional air valve, redirecting the compressed air to the

opposite inner chamber.

Principle of Pump Operation

UNIVERSAL ALL AODD

2: INSTALL & OP

hd20fnmdl1sm-rev0717

sa ndp ipe rpu mp.c om Model HD20F Non-Metallic • 9

Installation and Start-Up

Locate the pump as close to the product being pumped as possible. Keep the suction line length and number of ttings to a minimum. Do not reduce the suction line

diameter.

Air Supply

Connect the pump air inlet to an air supply with sufcient capacity and pressure to achieve desired performance. A pressure regulating valve should be installed to

insure air supply pressure does not exceed recommended limits.

Air Valve Lubrication

The air distribution system is designed to operate WITHOUT lubrication. This is the standard mode of operation. If lubrication is desired, install an air line lubricator

set to deliver one drop of SAE 10 non-detergent oil for every 20 SCFM (9.4 liters/sec.) of air the pump consumes. Consult the Performance Curve to determine air

consumption.

Air Line Moisture

Water in the compressed air supply may cause icing or freezing of the exhaust air, causing the pump to cycle erratically or stop operating. Water in the air supply can

be reduced by using a point-of-use air dryer.

Air Inlet and Priming

To start the pump, slightly open the air shut-off valve. After the pump primes, the air valve can be opened to increase air ow as desired. If opening the valve

increases cycling rate, but does not increase the rate of ow, cavitation has occurred. The valve should be closed slightly to obtain the most efcient air ow to pump

ow ratio.

Troubleshooting Guide

For additional troubleshooting tips contact After Sales Support at [email protected] or 419-524-8388

Symptom: Potential Cause(s): Recommendation(s):

Pump Cycles Once Deadhead (system pressure meets or exceeds air

supply pressure).

Increase the inlet air pressure to the pump. Pump is designed for 1:1 pressure ratio at zero ow.

(Does not apply to high pressure 2:1 units).

Air valve or intermediate gaskets installed incorrectly. Install gaskets with holes properly aligned.

Bent or missing actuator plunger. Remove pilot valve and inspect actuator plungers.

Pump Will Not Operate

/ Cycle

Pump is over lubricated. Set lubricator on lowest possible setting or remove. Units are designed for lube free operation.

Lack of air (line size, PSI, CFM). Check the air line size and length, compressor capacity (HP vs. CFM required).

Check air distribution system. Disassemble and inspect main air distribution valve, pilot valve and pilot valve actuators.

Discharge line is blocked or clogged manifolds. Check for inadvertently closed discharge line valves. Clean discharge manifolds/piping.

Deadhead (system pressure meets or exceeds air

supply pressure).

Increase the inlet air pressure to the pump. Pump is designed for 1:1 pressure ratio at zero ow.

(Does not apply to high pressure 2:1 units).

Blocked air exhaust mufer. Remove mufer element, clean or de-ice, and re-install.

Pumped uid in air exhaust mufer. Disassemble pump chambers. Inspect for diaphragm rupture or loose diaphragm plate assembly.

Pump chamber is blocked. Disassemble and inspect wetted chambers. Remove or ush any obstructions.

Pump Cycles and Will

Not Prime or No Flow

Cavitation on suction side. Check suction condition (move pump closer to product).

Check valve obstructed. Check Valve not seating

properly or sticking.

Disassemble the wet end of the pump and manually dislodge obstruction in the check valve pocket.

Clean out around valve and valve seat area. Replace valve seat if damaged.

Valve(s) / seat(s) damaged or attacked by product. Check Chemical Resistance Guide for compatibility.

Check valve and/or seat is worn or needs adjusting. Inspect check valves and seats for wear and proper setting. Replace if necessary.

Suction line is blocked. Remove or ush obstruction. Check and clear all suction screens or strainers.

Excessive suction lift. For lifts exceeding 20’ of liquid, lling the chambers with liquid will prime the pump in most cases.

Suction side air leakage or air in product. Visually inspect all suction-side gaskets and pipe connections.

Pumped uid in air exhaust mufer. Disassemble pump chambers. Inspect for diaphragm rupture or loose diaphragm plate assembly.

Pump Cycles Running

Sluggish / Stalling,

Flow Unsatisfactory

Over lubrication. Set lubricator on lowest possible setting or remove. Units are designed for lube free operation.

Icing. Remove mufer screen, de-ice, and re-install. Install a point of use air drier.

Clogged manifolds. Clean manifolds to allow proper air ow.

Deadhead (system pressure meets or exceeds air

supply pressure).

Increase the inlet air pressure to the pump. Pump is designed for 1:1 pressure ratio at zero ow.

(Does not apply to high pressure 2:1 units).

Cavitation on suction side. Check suction (move pump closer to product).

Lack of air (line size, PSI, CFM). Check the air line size, length, compressor capacity.

Excessive suction lift. For lifts exceeding 20’ of liquid, lling the chambers with liquid will prime the pump in most cases.

Air supply pressure or volume exceeds system hd. Decrease inlet air (press. and vol.) to the pump. Pump is cavitating the uid by fast cycling.

Undersized suction line. Meet or exceed pump connections.

Restrictive or undersized air line. Install a larger air line and connection.

Suction side air leakage or air in product. Visually inspect all suction-side gaskets and pipe connections.

Suction line is blocked. Remove or ush obstruction. Check and clear all suction screens or strainers.

Pumped uid in air exhaust mufer. Disassemble pump chambers. Inspect for diaphragm rupture or loose diaphragm plate assembly.

Check valve obstructed. Disassemble the wet end of the pump and manually dislodge obstruction in the check valve pocket.

Check valve and/or seat is worn or needs adjusting. Inspect check valves and seats for wear and proper setting. Replace if necessary.

Entrained air or vapor lock in chamber(s). Purge chambers through tapped chamber vent plugs. Purging the chambers of air can be dangerous.

Product Leaking

Through Exhaust

Diaphragm failure, or diaphragm plates loose. Replace diaphragms, check for damage and ensure diaphragm plates are tight.
