1.2 General Description
UNIBLOC-PD is a positive displacement rotary lobe pump. It may be supplied with a drive unit (figure 1.0) or without a drive
unit (figure 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 4 different series; 5000 series with stainless steel bearing housing, 4000A with an
anodized aluminum bearing housing or 4000B with a painted aluminum bearing housing and 3000 series with steel bearing hous-
ing. Different models are available from each series. Table 1.0 shows the pump bearing housing and model relation. Each model
can be mounted with the inlet and outlet ports in horizontal or vertical orientation. The orientation can be modified using either a
foot for horizontal or pedestal for vertical. Port orientation should be specified when ordering.

The UNIBLOC-PD port positions are designed to accommodate both vertical and horizontal product flow. Model 200-275 has a
bracket with an integrated foot and can be rotated 90° to change port orientation. Models 300-575 have a pre-drilled bearing hous-
ing. This allows custom installation, standard feet for horizontal ports, or a standard pedestal for vertical port orientation.
The pump is designed to operate in both directions without modifications. See figure 1.2
