Deltec Peristaltic Pump - PP32ML

Deltec Peristaltic pumps, available from Swell UK, are a simple and controllable way of metering water within the aquarium, the new range of Peristaltic pumps are based on reliability and function rather than to the lowest price and now include an ability to adjust the dosing time.

The pumps are not prone to variations in output and pressure like a standard impellor driven pump. This makes them ideal for feeding calcium reactors, nitrate reactors and for metering chemicals or trace elements and now with optional timer the continuous flow of liquid can be adjusted for variable dosing periods.

Product Features at a glance:

There are two sizes of pumps available in this range, 32ml/min and 150ml/min, both models are rated for continuous operation.

The pumps are fixed speed and are designed to produce a variable flow rate by switching the pump off and on over short time intervals using an optional timer rather than by adjusting the speed with a variable motor.

The reason for this is that variable pumps from almost any manufacturer will have a lifespan of approximately 6-12 months if used continuously, due to wearing of the carbon brushes on the DC motor which have a finite life and can not be replaced.

In addition there are low cost peristaltic pumps that are designed for intermittent use and are not designed to have the continuous duty of these industrial/medical grade models

All D-D pumps use Santoprene tubes for their longevity compared to cheaper silicone tubes which can split during extended operation.

All pumps use 3 or 4 rollers which will ensure that the tube is always nipped in at least one point.

Other lower cost pumps with 2 bearings can easily back siphon if the pump is stopped.*

Optional plug in timer to allow the user to program the unit to fine tune the output. The units on or off timers can be set to run individually for periods of up to 100 seconds.
