Description
The Pentax PM45-A 110v (code 022-403) is an automatic booster pump for sites and buildings where equipment runs from a 110v supply. It uses the same 0.37 kW Pentax peripheral pump and Watertech Presscontrol as the 230v model, giving up to 40 l/min and up to 40 metres of head, with about 21 metres at 20 l/min. Connections are a 1″ female thread on the pump inlet and a 1″ male thread on the controller outlet. The pump starts when an outlet opens and stops shortly after it closes.
For homes and premises with a standard 230v socket, the PM45-A 230v is the same pump and controller. Choose this 110v version when the unit must run from a site transformer.
The pump end is a Pentax PM 45A peripheral pump with a cast iron pump body and motor bracket, a brass impeller with radial blades, an AISI 416 stainless steel motor shaft and a ceramic and graphite mechanical seal. Pentax gives the pump a maximum operating pressure of 6 bar. The Watertech Presscontrol is fitted to the pump outlet and comes pre-wired, ready to plug in.
Features
- Pump and Presscontrol supplied as one pre-wired unit
- Runs from a 110v site supply
- Starts when an outlet opens and stops shortly after it closes
- Stops the pump if the water supply runs out
- No pressure vessel needed for normal use
- Up to 40 m head and 40 l/min from a 0.37 kW motor
Applications
- Boosting showers and basins in site welfare units
- Pressurising a supply drawn from a bowser or storage tank on site
- Washing points on construction and maintenance sites
- Temporary water supplies where only 110v is available
The PM45-A is for clean water only. Do not use it for water containing sand, grit or fibres, for sewage or drainage, or for oils and chemicals. Install it with the water level above the pump inlet; it is not intended for lifting water from a well or borehole, and it should not be connected directly to the water main. For several bathrooms or outlets running at once, choose a larger booster pump.
Pentax PM45-A range
| Model | Supply | Motor output P2 (kW) | Max head (m) | Head at 10 l/min (m) | Head at 20 l/min (m) | Head at 30 l/min (m) | Max flow (l/min) | Inlet x outlet | Code |
|---|---|---|---|---|---|---|---|---|---|
| PM45-A 230v | 230v single phase | 0.37 | 40 | 30 | 21 | 13 | 40 | 1″ F x 1″ M | 022-402 |
| PM45-A 110v | 110v single phase | 0.37 | 40 | 30 | 21 | 13 | 40 | 1″ F x 1″ M | 022-403 |
Head figures are Pentax’s published performance for the PM 45A pump at 230v, which our curve for both versions follows. At 40 l/min the pump gives only about 5 metres, so plan on 30 l/min or less for useful pressure.
