MOUNTING

The FLOJET G70C self-priming pump should be mounted in a dry and adequately ventilated area. This pump can be mounted several feet from the tank, above or below the fluid level. For most applications, no more than 4 feet above the fluid level is recommended. Note:

This is not a submersible pump.

Secure Pump to desired fixture by inserting screws through the rubber grommets in the baseplate of the pump.

Ports must be

facing down. The pump must be protected by a housing able to withstand the impact of a steel half ball of 25mm with a mass of 1Kg and an energy of 7J. Refer to EN 13463-1 Par 13 for further details.

HOSE CONNECTIONS

Liquid In - Use 3/8”, 1/2”, or 3/4” I.D. reinforced hose or equivalent. Avoid sharp bends that could restrict flow or cause hose to collapse under vacuum.

Liquid Out - Use 3/8”, 1/2”, or 3/4” I.D. reinforced hose for discharge tube. 3/4” I.D. hose must use 90° elbows when using large muffler.

Air In - Make sure air regulator is set at zero. Use reinforced

1/4” I.D. hose. Connect “Air In” to air supply fitting on regulator. If pumps are installed in an enclosed area, it is recommended to connect a hose to the air discharge port

(exhaust) and vent air to atmosphere (Requires small exhaust port PN# 20756103B not included).

PLUMBING

Use a flexible hose to avoid excess stress on pump ports.

DO NOT crimp or kink hose.

All hose should be the same size as the pump port fittings.

All fittings and hose must be compatible with fluid being

FLEXIBLE

HOSE

RIGID

PIPE pumped. It is recommended to use plastic fittings only.

The use of check valves in the plumbing system could interfere with the priming ability of the pump. If unavoidable, check valves in the pumping system must have a cracking pressure of 2 PSI or less.

Use a minimum 40 mesh strainer or filter in the tank or pump inlet line to keep large foreign particles out of the system.

Liquid inlet port must be equal to or larger than the liquid outlet port.

OPERATION

At start-up, regulate air pressure to desired setting. For most installations 20 PSI (1.4 bar) inlet will be adequate, although DO NOT go below 20 PSI. Pump will operate according to air supply. Flow and pressure can be adjusted by increasing or decreasing air pressure to accommodate varying product viscosities, length of lines or other installation conditions. Review flow curves located on page

1 for further assistance. High viscosi ty fluids and hose length will limit priming distance.

Compressors must have dryers and/or a water separator in the air distribution system. Pumps that fail due to water in the air chamber will not be covered under the limited warranty.

Plastic air inlet ports do not have a check valve. Prior to cleaning or servicing, purge the pump by carefully tilting the pump so ports are facing up and remove suction line from source. Turn air off and disconnect air inlet line. (Standard brass air inlet ports have a check valve).

DISASSEMBLY PROCEDURE

First, remove inlet air line, muffler and suction/discharge line from the pump. This is accomplished by using a flatbladed screwdriver to slide the retaining clips away from the air inlet, muffler and suction/discharge fittings and pulling the fittings away from the pump body. Now remove the muffler by sliding the retaining clip away from the muffler base and pulling the muffler out of the pump body.

Using a Phillips screw driver remove the seven (7) screws from the front end cap followed by the (7) screws from the rear end cap. With the front end cap facing up and the rear end cap facing down on the workbench, position a flat bladed screw driver into the slot located above the muffler port and just below the pad marked Air/C02 and lift off the front end cap. The rear end cap can be removed by placing the flat bladed screwdriver under the fully opened port retaining clip and lifting off.

Note the position of the suction and discharge valves before removing them from the pump body. The first diaphragm is removed from the pump shaft by unscrewing in a counter clockwise direction. The second diaphragm is removed by placing the flat tip of a screwdriver into the exposed slot at the end of the pump shaft and unscrewing the diaphragm from the shaft. To remove the flange housing, place the tip of the flat bladed screw driver into the air bleed hole on the lower side of the flange housing and lift up the lower end separating the flange housing from the pump body.

The slide valve assembly and pump shaft can be removed by simply pulling them from the pump body. The pump shaft then can be removed from the slide valve yoke assembly.

REASSEMBLE PROCEDURE

Assemble the slide valve and pump shaft with the yoke placed between the (2) bumpers on the pump shaft. Install the slide valve/pump shaft assembly into the pump body making sure the O-rings in the slide valve are in place. To install the flange housing, prelube the o-ring with Parker

Super “O” Lube and install on flange housing and place housing over the pump body aligning the flange housing with the pump body ribs pressing it into place.

Install the first diaphragm and O-ring on to the pump shaft by threading on to shaft using a flat blade screwdriver to hold the pump shaft until the diaphragm is tight. Install the second diaphragm and O-ring on to the pump shaft turning clockwise until tight.

Install the suction valves with springs facing into the pump body and the discharge valves with the springs facing out.

See arrows on pump rear end cap below suction and discharge ports.

Install the port retainer clips (large) into the pump end cap

(mounting base) and install the seven (7) Phillips screws into pump body and cross tighten until snug and then cross torque to 22-24 inch pounds. Install port retaining clips

(small) into the pump body with tabs facing out. Position the front end cap and install the seven (7) Phillips screws into pump body and cross tighten until snug and then cross torque to 22-24 inch pounds.

Install the muffler in the center port by pushing it in and sliding the retainer clip into place. Install the suction and discharge ports and the air inlet port fitting and slide the retainer clips in place. Check for leaks.

GENERAL SAFETY INFORMATION

Follow all safety codes and the Occupational Safety and

Health Act (OSHA).

These User Instructions contain specific safety markings where non-observance of an instruction would cause hazards.

The specific safety markings are:

This symbol indicates safety instructions where non-compliance would affect personal safety and could result in serious injury.

CAUTION

This symbol indicates safety instructions where noncompliance will involve some risk to safe operation and personal safety and would damage the equipment and or property.

Do NOT pump Gasoline or flammable fluids with flash point below 98°F (37°C) Explosion or serious injury may occur.

Incompatible fluids may cause premature failure of the pump. It is the customer’s responsibility to ensure that fluids are compatible with pump materials.

If used with ventilated.

C02 or N2 be sure the area is well

CAUTION

If pump is to be used in high flow, low pressure applications, adjust air pressure to 20 PSI (1.38 bar) above discharge pressure.

CAUTION

Pressure.

Do NOT Exceed 100 PSI (6.9 bar) Air Inlet

CAUTION

Continuous operation above 120

°F (48.9°C) will reduce pump life.

When using high pressure gas tanks make sure a secondary regulator is used to avoid accidental damage to pump.

CAUTION

CAUTION

Do not clean or service FLOJET pumps, hoses or valves while the system is pressurized.

This is not a submersible pump - use only in dry environments.

PREVENTIVE MAINTENANCE TIPS

Tips to help prolong your pump’s life.

• If pumping liquid other than water, pump should be flushed with water (if applicable) after every use.

• Before freezing conditions occur, pump must be liquid free.

• If mounting pump in an outdoor environment, shield pump from environmental extremes (i.e. sunlight, water from washdown spray, rain, etc.). Avoid high heat and humid installations.

• When using an air compressor, use an inline air dryer

(PN# FJ520B) before the pump to limit water build-up.

WARRANTY

CAUTION

Inlet air must be dry and oil free - use an air/oil filter and air dryer.

CAUTION

Mount with ports facing down.

To Reduce the risk of static sparking, ground the pump and all other equipment used or located in the pumping area. Check your local electrical code for detailed grounding instructions for your area and type of equipment.
