Cold Water Booster Sets
Our cold water booster sets are built to meet the stringent specifications used
in the construction and process industries. Solid state controls with integration
into BMS and remote monitoring and management systems are used as standard or
more traditional electro-magnetic control panels can be supplied as an option.
Sets supplied for use with potable water are built using WRAS Approved components
throughout (the P variant) or alternatively standard cold water sets can be supplied
for use with non-potable water (the C variant) .

Pumpac booster sets are individually designed for each and every job taking into
account required flow-rate and pressure, the expected demand pattern, integration
with other equipment on site and physical constraints. As a result we will build
packages in many configurations to suit the requirements of the application but
where possible, in the interest of economy and efficiency, pumpsets are developed
from standard configurations.
In deciding on the type of pumpset required for an apllication, firstly it is
necessary to identify what the principle water supply requirement is within the
building or industrial premises:- In deciding on the type of pumpset required for an apllication, firstly it is
necessary to identify what the principle water supply requirement is within the
building or industrial premises:-
-
To boost a low pressure mains supply to feed a header tank or auxiliary equipment
such as fire hoses, cooling plant or washing facilities.
-
To stabilise a fluctuating mains supply.
-
To re-establish pressure where a Water Byelaws break tank is required.
Once the purpose has been clearly defined it should be possible to determine
the most suitable type of pump-set, the pump control arrangement and the size
of accumulator by considering the following three key questions:-
- Is 100% standby cover required if a pump fails or is less acceptable? If 100% standby cover is required a Duty/Standby or Duty/Assist/Standby pump
arrangement is required, if only partial cover is required a Duty/Assist arrangement
using two half sized pumps would probably be most suitable depending on the design
flowrate. If no standby cover is required the most economical solution will probably
be a C/PRE Series set or C/PDOM Series with a single pump.
- Does the demand pattern require similar flow-rates throughout the day, e.g. a
booster set feeding a header tank? If so a fixed speed system using a small accumulator will be appropriate, if
this is generally the case but much smaller flows are also required from time
to time then a large storage accumulator or small jockey pump may be required
to meet these small demands.
- Is the demand pattern so variable that a Jockey/Duty or Duty/Assist arrangement
with large accumulator would be inefficient for a majority of the time? If so a variable speed pump set is probably required. With some larger systems
it may also be appropriate to include a jockey pump within a variable speed set.
