1.1 UNPACKING
After unpacking, the pump should be checked for any damage that may have
occurred during shipment. Damage should be reported to the carrier
immediately.
The following items should be included within the shipping container:
1.2 UTILITIES / HOOK-UP
It is recommended that the pump be positioned within 15° from level to maintain
self-priming ability and pumping efficiency. Allow sufficient room for tubing
connectors. The pump mounts on a quick-change base for easy installation.
The pump has dual exhaust locations on the backside of the base. The exhaust
locations require 1/2” (12mm) minimum clearance behind the control base. Care
should be taken to elevate the pump whenever possible to help prevent flooding
when the pump is located in a wet bench plenum. For remote exhaust
connection see Section 1.5.
Air Inlet: 1/4” FNPT (3/8” Dia. [8mm] supply tube minimum).
Fluid Ports: Inlet/Outlet Fluid Fittings and Surge Suppressor require torqueing
during pump installation. See Section 2 for hook- up diagram and
torque values.
Air Supply: 20-80 psig (1.4 – 5.5 bar) clean dry air or nitrogen (see
Performance Charts, Section 3.1).
MAXIM 50E/U PUMP OPERATION / MAINTENANCE MANUAL PAGE 3
Figure 1-1
ATTENTION: The pump should be operated with clean, dry air or nitrogen.
Particulate, water and oils in the air supply can damage the pump.
NOTE:
1. It is recommended that a filter be placed on the discharge side of the pump.
2. Although extensive efforts are made to deliver pumps to our customers
completely dry, new pumps may contain residual moisture from their final DI
water test.
Recommended Maximum Operating Levels: See Error! Reference source
not found.

1.3 PROBE ASSEMBLY INSTALLATION (E MODEL ONLY)
Optic Cable: 1mm core; 1/4” PFA protective tubing.
Install seal into head.
Install probe assembly into head.
Thread probe cap into head hand tight only, no tool needed.
Connect fiber optic cable to sensor. NOTE: Minimize bends in fiber optic
cable to 2” radius minimum to help ensure optimum signal strength. NOTE:
Standard cable length is 15 ft. [4.57 meters].
Figure 1-2
1.4 PLC CONTROL SCHEMATIC
Shown below is an example of the fiber optic end of stroke detection for a Maxim
Pump. The Programmable Logic Controller (PLC) control schematic shown will
allow the Maxim to be controlled by a PLC. Some of the features that can be
programmed are:
Start and stop pump
Monitoring approximate flow rate
Leak sensing
High and low flow rate detection
Preventative maintenance counter
Cycle counting
Oscillator control override
NOTE: See examples of ladder logic programs in Section 4.10.

1.5 REMOTE EXHAUST HOOK-UP
Remove existing Muffler Assembly from pump base.
Install Exhaust Plugs in Quick Exhaust Ports.
Remove Pipe Plug (1/4” NPT) from the pump base. Install the appropriately
sized fitting and tubing (not provided) to remote exhaust.
NOTE: To maintain optimum pump performance use 3/8” tubing minimum at a
length of 10 ft. maximum.

NOTE: See Surge Suppressor Operation Manual for detailed installation
instructions.
2.3 OPTIONAL LEAK SENSING
2.3.a Installation
Remove plug and seal from port. Probe is self-sealing.
Install probe assembly into leak sensor port.
Thread probe cap into port. (NOTE: Do not over tighten; damage to threads
will occur.)
Push protective tubing into probe cap.
Connect fiber optic cable to sensor (NOTE: Minimize bends in fiber optic
cable to 2” radius minimum to help ensure optimum signal strength.) Fiber
optic cable can be cut to desired length using the cable cutter provided.
2.3.b Sensor Signal Specifications
The sensor signal is normally closed. In the event of a leak, no light signal is
returned to the sensor.
NOTE: See your fiber optic sensor installation instructions for proper hook-up
and adjustment.

3 START-UP
Pump air supply pressure should be regulated. (See : Pressure vs. Fluid
Temperature Chart)
Open the fluid suction (IN) line valve, if necessary.
Open the fluid discharge (OUT) line valve, if necessary.
Start with air regulator at low (> 20 psi) pressure setting. Increase pressure
to attain desired flow, up to the maximum rating (See Section 3.1).
Table 1: Consumption / Efficiency can be used to determine approximate air
consumption.
Refer to Troubleshooting, Section 5, if pump fails to start.
ATTENTION: Prolonged periods (>5 minutes) of dry running can damage critical
internal pump parts.
CAUTION: When handling potentially dangerous fluids under pressure,
the pump and its fittings should be placed in a compatible enclosure.
3.1 PERFORMANCE CHARTS
Pumping capacity is a function of air supply pressure and volume, suction head,
suction line restrictions, discharge head, discharge line restriction, and fluid
specific gravity and viscosity.
Table 1: Consumption / Efficiency
NOTE: Specification to be used to size regulators and control valves.

NOTE:
1. This graph is not representative of all operating conditions - customer’s
specific application results may vary.
2. Be sure that fittings and tubing used are capable of these operating
conditions.
