IVAC® Volumetric Pump (Models 571 & 572) 34/104 1000SM00018 Issue 2
Routine Maintenance
Physical Inspection and Clean
To ensure the pump remains in good operating condition, it is important to keep it clean and carry out the routine
procedures described below.

Routinely clean the pump, especially if spillage has occurred.

Unplug the power cord from the AC wall outlet before cleaning. Do not allow fluids to enter the pump case.
 Clean the exterior surfaces (the outer case top, bottom, sides; the switch panel, the front panel and inside the door)
with a cloth dampened with warm water, or a mild non-abrasive detergent (such as commercially available dish
cleaning liquid) mixed with water.
Note: Alcohol, ammonia, acetone, benzene, phosphoric acid, xylene and similar solvents can erode (wear away pit)
or otherwise damage the cam followers and other surfaces of the pump. The cam followers must be kept clean using
a solution of warm water and a mild non-abrasive detergent, and inspected for possible erosion according to the
procedure outlined on the following page, see 'Inspecting and Cleaning the Mechanism'.
Before cleaning always switch OFF and disconnect from the AC power supply. Never allow fluid to
enter the casing and avoid excess fluid build up on the pump.
Keep pump upright to prevent fluid entry around the pressure transducer.
Do not use aggressive cleaning agents as these may damage the exterior surface of the pump.
Do not steam autoclave, ethylene oxide sterilise or immerse this pump in any fluid.
Do not use alcohol or alcohol-based
cleaning agents on the surface of the
pressure transducer.
 Check that labels are flat, legible and fully adhered. Replace as necessary.

Inspect the case for loose or damaged components and replace if necessary.

Inspect the circuit breaker for damage.

Inspect the AC power supply plug and cable for damage.

Inspect the door assembly for damage. Check that the door pivots freely and latches securely.

Inspect the mechanism for fluid spill residue or foreign matter. Open the door and inspect the exposed cam followers,
the pressure plate and tubing pincher. Clean any surfaces where solution has accumulated.
 Clean crevices (
A
) using a soft-bristle brush,
such as a one-inch paint brush, dipped in the
mild detergent solution (see above). Pat dry
all moistened areas with a cloth then leave the
door open for at least 15 minutes to air-dry
crevices.

Manually actuate points (
B
) by pressing then
releasing each part to verify that it moves freely.

After cleaning is complete, if required and
where heavy spillage has required extensive
cleaning, lubricate the tubing pincher and the
sides of the mechanism ( C ) using a silicone-
based grease.
