5.1 MOUNTING

The Flojet M50 pump is self-priming

and should be mounted in a dry and

well-ventilated area. This pump should

be located within 8 ft (2.44 m) of the

bag-in-box and mounted vertically. May

be mounted above or below the bag.

Note: This is not a submersible pump.

Secure the pump utilizing appropriate screw sizes through the

slotted mounting holes (two) on the rear of the pump body. Pump

should be mounted vertically with the ports horizontal.

5.2 HOSE CONNECTIONS

Liquid In – Use 3/8" (9.5 mm) ID vinyl or tygon beverage hose or

equivalent. Avoid sharp bends that could restrict flow or cause hose

to collapse under vacuum.

Liquid Out – Use 1/4" (6.3 mm) ID reinforced beverage hose for

discharge tubing.

5.3 PLUMBING

Use a flexible hose to avoid excess stress on pump fittings. Do not

crimp or kink hose.

All hoses should be the same size as the pump fittings. All fittings

and hoses must be compatible with fluid being pumped.

Flexible hose

6.0 Troubleshooting

Symptom

Pump will not start (stalls)

Pump runs, but no fluid

Pump leaks through

exhaust port

Flow rate is low

Pump leaks

7.0 Pump cleaning / sanitizing

The pump and the complete dispensing system should be cleaned and sanitized regularly as recommended by the local health authority,

syrup concentrate manufacturer, or equipment manufacturer (whichever has jurisdiction). Refer to Process Specification #91013934 for

procedure that meets the NSF listed sanitizing requirements for the Flojet pump only.

2. Contaminated air supply

3. Empty BIB or BIB connector not fully engaged

4. Pinched product inlet/outlet tubing

1. A leak or break in the product inlet line

2. A leak or break in the product discharge line

1. Leak at upper exhaust port o-ring

2. Contaminated air supply (moisture in air inlet)

1. Tubing or hose is damaged or blocked

2. Check viscosity or medium being pumped

1. Pump housing screws not torqued

adequately

5.4 OPERATION

DANGER: ASPHYXIATION HAZARD.

If CO

or N

the area is well ventilated or gas is exhausted to out-

side atmosphere via hose.

CAUTION: If pump is to be used in high flow, low

pressure applications, adjust gas pressure to 20 PSI

(1.38 Bar) above discharge pressure.

CAUTION: Continuous operation at 120°F (49°C)

will reduce pump life.

To start operation, regulate gas pressure to desired setting. For

most installation 20 to 70 PSI (1.38 to 4.83 Bar) will be adequate.

Open discharge valve to purge air from the system. Pump will

now operate automatically by starting and stopping on demand,

as beverages are served and maintaining constant pressure at

the dispensing valve. Product flow and pressure can be adjusted

by increasing or decreasing gas pressure to accommodate varying

product viscosities, length of lines or other installation conditions.

Do not exceed 70 PSI (4.8 Bar) gas pressure.

Review flow curves for more information. High viscosity fluids and

hose length will limit priming distance.

NOTICE: Removing the yellow clip will disengage the air in-

let fitting and remove the driving pressure to the pump. This

should be done only if there is a need to immediately shut-

down the pump until a qualified service technician arrives.

Pumps that fail due to water in the air chamber will not be covered

under the limited warranty.
