Pump hunting protection
In negative head systems all the discharge
pipework after the pump is pressurised. In
such systems there exists the possibility the
pump will hunt ON-OFF-ON etc at intervals.
This will happen:
• if all outlets are not fully closed
• if there is a leak at a connection
• if boosted toilets are not fitted with
equilibrium ball valves
• or as residual hot water contracts in long
pipe runs.
The irritating effects of hunting are
cushioned by the pressure vessel which is an
inbuilt feature of ESP CPV pumps.
Stored hot water volume
In calculating the volume of the stored
hot water requirement it is important to
consider:
• number of bathrooms, with particular
attention to the size of the bath
• number of persons in household
• time spent in shower e.g. 10mins in a
5 gall/minute shower will use up 50 galls
of the cold water storage capacity approx
60% of which (30 gallons) will be hot
water from the cylinder.
Stored hot water temperature
Extract from BS5546:1990 (Current)
“The mean temperature of the stored water
should not normally exceed 60°C and in
a combined central heating and domestic
hot water system it is recommended that
the stored water temperature is controlled
independently from that on the primary
circuit”.

Extract from BS6700:1997
“Under normal conditions the
temperature of stored hot water should
never exceed 65°C. A stored hot water
temperature of 60°C is considered sufficient
to meet all normal requirements and will
minimise scale deposits in hard water areas”.
Effective control of stored hot water is simply
achieved by use of a cylinder thermostat and
zone valve or direct acting thermostatic valve
(e.g. tapstat).
In systems where the stored hot water
temperature is not controlled eg Aga solid
fuel appliance or very crudely by the boiler
thermostat, use a HWS Blending valve
controller.
HWS Blending valve controller
The HWS Blending valve controller is
designed to protect booster pumps in
systems where the temperature of the stored
hot water is uncontrolled – see below.

General specification
Applications
All Salamander pumps are designed to boost
low pressure hot and cold supplies from
tank-fed services.
Voltage
220-240 volts 50 Hz.
Motor type
Capacitor start and run induction type
motor with stainless steel shaft and in-built
resetting thermal protection (complies with
BS5000 part 11).
Pump materials
All moulded components are manufactured
from Acetal Copolymer.
Maximum head
ESP 50 CPV and ESP 55 CPV 5 metres
All other pumps
10 metres
Pumps fitted with RCM3 maximum 3 metres
static head.
Pump noise
With the technological advances achieved
in Right pumps and ESP pumps, Salamander
has taken another step forward in the quest
to supply all our customers with even quieter
centrifugal pumps. Despite this no pump is
completely silent.
Correct installation will minimise vibration
and transmission noise.
Mechanical seals
Scale deposits in water supplies can cause
the mechanical seal to stick if left for long
periods without use. We recommend the
pump be ran at least five minutes every
four weeks to ‘exercise’ all working parts.
Connections
3⁄4” BSP male.
Initiation
Fully automatic, flow switch operated,
requiring 1 litre in 30 sec per side or
2 litre in 30 sec mixed. Except Right ESP CPV
pumps when required to operate in negative
head mode.
Temperature
Maximum fluid temperature 65ºC.
Standards and approvals
Splash proof rating IPX2.
Complies with the requirements of current
British and European safety standards for
household and similar electrical appliances.
Complies with European Community
Directives (CE).

continuous development and reserves the
