Vertical, multistage centrifugal pump with inlet and outlet ports on same the level (inline). Pump materials in contact with the liquid are in high-grade stainless steel. A cartridge shaft seal ensures high reliability, safe handling, and easy access and service. Power transmission is via a rigid split coupling. Pipe connection is via combined DIN-ANSI-JIS flanges. The pump is fitted with a 3-phase, fan-cooled, permanent-magnet, synchronous motor. The motor efficiency is classified as IE5 in accordance with IEC 60034-30-2. The motor includes a frequency converter and PI controller in the motor terminal box. This enables continuously variable control of the motor speed, which again enables adaptation of the performance to a given requirement. An operating panel on the motor terminal box enables setting of required setpoint as well as setting of pump to "Min." or "Max." operation or to "Stop". The Grundfos Eye indicator on the operating panel provides visual indication of pump status:

Plato's dialogue about the physical world
Format: Paperback
The two biggest topics in the Timaeus are astronomy and the elements of bodies, which are constructed using triangles and the tetrahedron, octahedron, icosahedron, and cube. I would like to see a translation of the Timaeus that uses it as a way to introduce all the astronomy that appears in the dialogue. Introducing the astronomy does not mean just talking in words about spheres or the zodiac or the ecliptic, but actually explaining how these were used by astronomers. Cornford has much to say, but to someone who has not learned any Greek astronomy his commentary will be opaque and hard to use. I didn't know the astronomy well enough to readily understand Cornford's explanations. I plan to learn more classical Greek astronomy, perhaps using Evans'
, and then read Waterfield's translation of the Timaeus
.
Before reading this you should have read the Republic and know some classical Greek natural philosophy, mathematics, and astronomy. Although Cornford's commentary makes the dialogue staccato, I am glad for it because I wouldn't otherwise have understood much of what Plato says. The Timaeus and the Parmenides are the two dialogues of Plato that one needs commentary to understand; the Parmenides demands the commentary because so much of what is happening depends on the original language, and the Timaeus demands the commentary because of all the things the reader is supposed to be familiar with.
The following is a list of topics I kept while reading the dialogue: theory of Forms 27d-28a, 51a-52a; harmonics 35b-36b; time 37c-38e, 39b-e; vision 45b-46c, 67c-68d; space 52b; surfaces 53c; weight 62d-63e; sound 67a-67c; physiology 70c-79e, 80d-86a; antiperistasis 79e-80c.

Helpful, but Waterfield is better for an intro
Format: Paperback
This is basically a scholarly paragraph-by-paragraph commentary on the Timaeus. It's really good for what it is, but I don't recommend it as your first introduction to the Timaeus -- rather, I recommend Waterfield:
http://www.amazon.com/Timaeus-Critias-Oxford-Worlds-Classics-ebook/dp/B006NTMD16
A problem with using Cornford as an introduction is that he comments on everything, and it's hard to figure out what the main themes are. I tried reading Cornford as an intro and gave it up, but once I'd read Waterfield I found Cornford extremely helpful both in elucidating passages further than Waterfield does, and in interpreting passages Waterfield doesn't cover. So if you're looking to learn about the Timaeus, I'd suggest Waterfield first and Cornford second (or Cornford alongside Waterfield).

Cornford's running commentary is arguably the best suited to fulfill this desire
Readers of any of Plato's works are bound to feel they might profit from various commentaries. His Timaeus, in particular, may be said to elicit such a hope because of number and intricacy of its details. Cornford's running commentary is arguably the best suited to fulfill this desire: it helps make clear the integrity of the dialogue as a whole and illumines the specific points along the way. Although this work is certainly dated, originally published in 1937, it is certainly one of the best full commentaries on the Timaeus.

Plato's view of the creation of the world
Format: Paperback
A cosmology is a narrative concerning the creation of the universe. Many ancient philosophers have written or elaborated this kind of work. The Platonic dialogue Timeus is an account of the work of the creator god (called the demiurge - or artisan) sculpting the chaotic material world in accordance with the immaterial model of the Ideas. But the text was written in a very hermetic and symbolic language, making its interpretation difficult or even impossible without the knowledge of the references and symbols used by Plato. This book is a complete translation of the text followed by a comprehensive commentary explaining in detail every passage. Francis MacDonald Cornford is one of the most important ancient philosophy scholars, and this work reveals his deep knowledge of Platonic and Greek thought. It is a must have for anyone interested in greek and Platonic philosophy.
