Details
The Aquacomputer Aqualis D5 150 mL Reservoir (34081) is a 150 ml tube reservoir that a Laing D5 pump mounts to directly. Its Delrin base part is the pump receptacle and serves as the D5 pump top. Pump, decouplers and fittings are not included.
Properties
- Pump
- Laing D5, mounted directly (not included)
- Capacity
- approx. 150 ml
- Ports
- G1/4
- Size
- approx. 80 x 80 x 185 mm, 220 mm high with the pump
Borosilicate glass tube
Every expansion tank of the aqualis series is equipped with a tube made of borosilicate glass. In contrast to Plexiglas, which is the acrylic glass commonly used for reservoir tubes, borosilicate glass has a very high hardness and scratch resistance and very low thermal expansion. Aquacomputer rates its chemical and thermal resistance as excellent. On the 100 ml and 150 ml variants the glass has an outer diameter of 50 mm and a wall thickness of 5 mm. The base part and the lid are Delrin, as on all bases and covers of the series, connected by a stainless steel rod.
Direct D5 mounting
The reservoir is designed for direct mounting of a Laing D5 pump at its base. A complete D5 pump is disassembled first: only the housing with the electronic components and the impeller are needed. With the gasket in the pump receptacle and the motor inserted, the clamping ring slides over the rear side and four countersunk M4 x 12 mm screws hold it. Four rubber decouplers (art. no. 41092, the Ultra Soft Pump Decoupling Kit) can go into the rear of the base part.
All 100 ml and 150 ml versions are also available with a nano coating, allowing water to pearl off from the inside of the glass tube. This article is the uncoated one.
What the loop needs
Add a Laing D5 pump or pump motor, for example the D5 Pump Core (41091) or the D5 Next RGB (41118). Return line and suction line both connect in the base of the reservoir, so you need a G1/4 fitting for each from our fittings section.
