1.2 General Description

FRONT COVER

UNIBLOC-PD is a positive displacement rotary lobe pump. It may be supplied with a drive unit (gure 1.0) or without a drive
unit (gure 1.1). When supplied with a drive unit it is called UNIBLOC-PD ASSEMBLY. Figure 1.0 indicates various parts of
an assembly. UNIBLOC-PD can be supplied in 3 dierent series; 5000 series with stainless steel bearing housing, 4000 with

aluminum bearing housing, and 3000 series with steel bearing housing. Each model can be mounted with the inlet and outlet ports

in horizontal or vertical orientation. Port orientation should be specied when ordering.

1.2.1 Limitation

The pump should be used for the duty for which it has been specied. The operating pressure,

speed and temperature limits have been selected at the time of order and MUST BE ADHERED
TO. These details are stated on the original order documentation. If not available, documenta­tion may be obtained from your supplier by referencing the pump serial number and/or invoice
number.

1.2.2 Noise Emission

Under certain operating conditions, pumps and/or drives and/or the systems within which they
are installed can produce sound pressure levels that exceed 80dB. In such cases ear protection
should be used.

1.2.3 Marking - CE

Figure 1.3 shows the tag that is attached on the pump bearing housing. If the tag were to be

lost for any reason you can nd the pumps serial number machined on the side of the bearing
housing. See gure 1.4. Always state the pump model and/or serial number when asking for

assistance.

Figure 1.3

1.2.4 Marking - Standard

Standard marking is machined on the side of pumps bearing housing. See gure 1.4 for details.
Pump size is machined on rotor housing next to the ports.

2.0 Before Start-Up

A. Are pump and motor alignment within proper tolerances?

B. Do motor and pump gearboxes have adequate amounts of oil?

C. Has the piping to the pump been installed correctly?

D. Has the system and all pipes been ushed and cleaned of all debris including weld slag and particles resulting from polishing

and grinding?

QUICK CHECK LIST

2.1 Pump Head

Remove the front cover and make sure that no particles are trapped inside the rotor housing. Check that the rotor bolts have been
securely tightened, if design provides such an option. If possible, make sure pump turns freely. Put back cover, making sure o-ring
remains in place, and securely tighten the four front cover nuts.

2.2 Direction of Flow

The pump is designed to operate in both directions without modications. Make sure that the proper direction of rotation applies.

2.3 Pipe Layout

When connecting pipes to the pump, make sure they are well supported, as the pump is not meant to serve this purpose. Keep in

mind that pipes lled with liquid are very heavy.

2.4 Port Positioning

UNIBLOC-PD is designed to accommodate both vertical and horizontal product through-puts.

2.5 Alignment and Mounting Suggestions

If a PTO pump shaft style is used, it is imperative that the pump and motor are properly aligned before operating. Misalignment
can lead to excessive wear and can cause the coupling to rupture. It can also create abnormal stresses on bearings and gears.

2.6 Clean the System Before Start-Up

Clean system of all debris before start-up. Any remaining particles larger than 0.002 in. (0.05 mm) can damage the pump if they

enter it. A ltering device installed before the pump inlet is highly recommended to insure safe and proper operation. Since such
a device will restrict the ow in to the pump, it is necessary to verify that the net positive suction head (NPSH) available is not

reduced below that required by the pump.
